When running a routing protocol, the Ethernet switch also functions as a router. The words “router” and the router icons covered in the following text represent routers in common sense and Ethernet switches running a routing protocol.

This manual deals with the S3600-EI series switches. The ospf, ospf-ase, and ospf-nssa commands are supported by the S3600-EI series, but not supported by any other S3600 Ethernet switch. This will not be mentioned again in this manual.

Table 1-2 Description on the fields of the display ip routing-table command

Field	Description
Destination	Destination address
Mask	Mask
Protocol	Routing protocol
Preference	Routing preference
Nexthop	Next hop address
Interface	Output interface, through which the data packets destined for the destination network segment are sent
State	Route state description:
	ActiveU	This is an active unicast route. "U" means "unicast".
	Blackhole	Blackhole route is similar to Reject route, except that a Blackhole route sends no ICMP unreachable message to the source end.
	Delete	The route is deleted
	Gateway	The route is not directly reachable.
	Hidden	The route is hidden. That is, the route exists, but it is hidden because it is unavailable for the moment due to some reason (e.g., a configured policy or a down interface) and is not expected to be deleted, and it can be restored later.
	Holddown	Holddown is a route redistribution policy adopted by some distance-vector (D-V) routing protocols such as RIP. Through Holddown, a routing protocol can avoid the flooding of error routes and deliver route unreachable messages accurately. It redistributes a certain route every a period of time regardless of whether the actually found routes destined for the same destination change. For more details, refer to the specific routing protocols.
	Int	The route is discovered by interior gateway protocol (IGP).
	NoAdvise	The routing protocol does not redistribute NoAdvise route when it redistributes routes based on the policy.
	NotInstall	Normally, the routing protocol selects the route with the highest preference from its routing table, places it in its core routing table, and redistributes it. Although the NotInstall route cannot be placed in the core routing table, it is possibly that it is selected and redistributed.
	Reject	Unlike the normal routes, the Reject route will discard the packets that select it as their route, and the router will send ICMP unreachable messages to the source end. Reject route is usually used for the network test
	Retain	When the routes from the routing table are deleted, the routes with Retain flag will not be deleted. Using this function you can set Retain flag for some static routes, so that they can exist in the core routing table.
	Static	The route with Static flag will not be cleared from the routing table after you save it and reboot the router. Generally, the static route configured manually in the router belongs to a Static route.
	Unicast	Unicast route
Age	Time to live, in the format of hour/minute/second (hh:mm:ss).
Cost	Value of the cost

Parameter

None

Description

Use the delete static-routes all command to delete all static routes.

The system will request your confirmation before it deletes all the configured static routes.

Related command: ip route-static and display ip routing-table.

Example

# Delete all the static routes in the router.

undo ip route-static ip-address { mask | mask-length } [ interface-type interface-number | next-hop ] [ preference preference-value ] [ reject | blackhole ] [ description text | detect-group group number ]*

View

System view

Parameter

ip-address: Destination IP address, in dotted decimal notation.

mask: Mask.

mask-length: Mask length. Since 1s in a 32-bit mask must be consecutive, a mask in dotted decimal notation can be replaced by mask-length, which is the number of the consecutive 1s in the mask.

interface-type interface-number: Next-hop outgoing interface. The packets sent to a null interface, which is a virtual interface, will be discarded immediately. This can decrease the system load.

next-hop: Next hop IP address of the route, in dotted decimal notation.

preference-value: Preference level of the route, in the range from 1 to 255. The default preference is 60.

reject: Indicates an unreachable route. If a static route to a destination has the "reject" attribute, all the IP packets destined for this destination will be discarded, and the source host will be informed that the destination is unreachable.

blackhole: Indicates a blackhole route. If a static route to a destination has the “blackhole” attribute, the outgoing interface of this route is the Null 0 interface regardless of the next hop address, and all the IP packet addresses destined for this destination are dropped without the source host being notified.

description: Provides a description for the current route.

detect-group: Specifies a detect group.

Description

Use the ip route-static command to configure a static route.

Use the undo ip route-static command to delete a manually configured static route.

By default, the system can obtain the subnet route directly connected to the router. When you configure a static route, if no preference is specified for the route, the preference defaults to 60, and if the route is not specified as reject or blackhole, the route will be reachable by default.

When configuring a static route, note the following points:

l If the destination IP address and the mask are both 0.0.0.0, what you are configuring is a default route. All the packets that fail to find a routing entry will be forwarded through this default route.

l You cannot configure an interface address of the local switch as the next hop address of a static route.

l You can configure a different preference to implement flexible route management policy.

Related command: display ip routing-table.

Example

# Configure the next hop of the default route as 129.102.0.2.

When running a routing protocol, the Ethernet switch also functions as a router. The word “router” and the router icons covered in the following text represent routers in common sense and Ethernet switches running a routing protocol.

2.1 RIP Configuration Commands

2.1.1 checkzero

Syntax

checkzero

undo checkzero

View

RIP view

Parameter

None

Description

Use the checkzero command to enable zero field check of RIP-1 packets.

Use the undo checkzero command to disable zero field check.

By default, RIP-1 performs zero field check.

According to the protocol (RFC 1058) specifications, some fields in RIP-1 packets must be zero and these fields are called zero fields. You can use the checkzero command to enable/disable zero field check of RIP-1 packets. When zero field check is enabled, if an incoming RIP-1 packet has a non-zero zero field, the packet will be rejected.

This command does not apply to RIP-2 packets because they have no zero fields.

Example

# Disable zero field check on RIP-1 packets.

Use the import-route command to import the routes of another protocol into RIP.

Use the undo import-route command to cancel the routes imported from another protocol.

By default, RIP does not import routes from other protocols.

The import-route command is used to import the routes of another protocol with a specified cost. RIP regards the imported routes as its own routes and transmits them with the specified cost. This command can greatly enhance the capability of RIP to obtain routes, thereby improving RIP performance.

If the cost value is not specified, routes will be imported with the default routing cost (set by the default cost command, ranging from 1 to 16). If the cost of an imported route is 16, RIP marks the route as HOLD DOWN (however, the route can still be used to forward packets), and continues to announce the route with this cost to other routers running RIP until the Garbage Collection timer times out (the timeout time defaults to 120 seconds).

Related command: default cost.

Example

# Import static routes with the cost of 4.

<H3C> system-view

2.1.10 network

Syntax

network network-address

undo network network-address

View

RIP view

Parameter

network-address: Address of the network for which RIP is enabled/disabled. It can be the IP network address of any interface.

Description

Use the network command to enable RIP on a specified interface.

Use the undo network command to disable RIP on the interface.

By default, RIP is disabled on any interface.

After a RIP routing process is started, it is disabled on any interface. To enable RIP routing on an interface, you must use the network command.

The undo network command is similar to the undo rip work command in function. But they are not identical.

Their similarity is that the interface using either command will not receive/transmit RIP routes any more.

The difference between them is that, in the case of undo rip work, other interfaces will still forward the routes of the interface on which the undo rip work command is executed. In the case of undo network, other interfaces will not forward the routes of the interface on which the undo network command is executed and it seems that the interface disappeared.

When the network command is used on an address, the effect is that the interface on the network segment at this address is enabled. For example, the results of viewing the network 129.102.1.1 with both the display current-configuration command and the display rip command are shown as network 129.102.0.0.

Related command: rip work.

Example

# Enable RIP on the interface with the network address 129.102.0.0.

Parameter

ip-address: IP address of the interface on the peer router with which routing information needs to be exchanged, in dotted decimal notation.

Description

Use the peer command to configure the destination address of the peer device with which routing information should be exchanged in unicast mode.

Use the undo peer command to cancel a unicast address.

By default, RIP does not send packets to any address in unicast mode.

This command is used to for non-broadcast networks to which protocol packets cannot be sent in broadcast mode. Generally you are not recommended to use this command.

Example

# Specify a unicast destination address of 202.38.165.1.

<H3C> system-view

Parameter

value: Preference level, ranging from 1 to 255. By default, the value is 100.

Description

Use the preference command to configure the route preference of RIP.

Use the undo preference command to restore the default preference.

Every routing protocol has its own preference. Its default value is determined by the specific routing policy. The preferences of routing protocols will finally determine which routing algorithm's routes will be selected as the optimal routes in the IP routing table. You can use this command to modify the RIP preference manually.

Example

# Specify the RIP preference as 20.

<H3C> system-view

System View: return to User View with Ctrl+Z.

Parameter

None

Description

Use the summary command to enable RIP-2 automatic route aggregation.

Use the undo summary command to disable RIP-2 automatic route aggregation.

By default, RIP-2 route aggregation is enabled.

Route aggregation can be used to reduce the routing traffic on the network as well as to reduce the size of the routing table. If RIP-2 is used, route aggregation function can be disabled with the undo summary command when it is necessary to broadcast subnet routes.

RIP-1 does not support subnet mask. Forwarding subnet routes may cause ambiguity. Therefore, RIP-1always uses route aggregation. The undo summary command is invalid for RIP-1.

Related command: rip version.

3.1 OSPF Configuration Commands

3.1.1 abr-summary

Syntax

abr-summary ip-address mask [ advertise | not-advertise ]

undo abr-summary ip-address mask

View

OSPF Area view

Parameter

ip-address: Network segment address.

mask: Network mask.

advertise: Specifies to advertise the aggregated route that match a specific IP address and mask.

not-advertise: Specifies not to advertise the aggregated route that match a specific IP address and mask.

Description

Use the abr-summary command to enable route aggregation on an area border router (ABR).

Use the undo abr-summary command to disable route aggregation on an ABR.

By default, an ABR does not aggregate routes.

This command is applicable to ABRs only and is used for route aggregation in an area. It allows the ABR to transmit an aggregated route to other areas.

Route aggregation means that routing information is processed by an ABR, which transmits only one route to other areas for each network segment configured with route aggregation. You can configure multiple aggregation routes in an area so that OSPF can aggregate multiple network segments.

Example

# Aggregate the routes in the two network segments, 36.42.10.0 and 36.42.110.0, in OSPF area 1 into one summary route 36.42.0.0 and transmit it to other areas.

Parameter

ip-address: IP address to be matched, in dotted decimal notation.

mask: IP address mask, in dotted decimal notation.

not-advertise: Specifies not to advertise the aggregated route matching the specified IP address and mask. If this argument is not provided, the aggregated route will be advertised.

tag value: Tag value, which is mainly used to control route advertisement via route-policy. It ranges from 0 to 4294967295 and defaults to 1.

Description

Use the asbr-summary command to configure the aggregation of imported routes by OSPF.

Use the undo asbr-summary command to cancel the aggregation.

By default, imported routes are not aggregated.

After the aggregation of imported routes is configured, if the local router is an autonomous system border router (ASBR), this command aggregates the imported Type-5 LSAs in the aggregation address range. If an NSSA is configured, this command also aggregates the imported Type-7 LSAs in the summary address range.

If the local router acts as both an ABR and a transit router in the NSSA, this command aggregates Type-5 LSAs transformed from Type-7 LSAs. If the router is not the router in the NSSA, the aggregation is disabled.

Parameter

simple: Uses simple text authentication mode.

md5: Uses MD5 cipher text authentication mode.

Description

Use the authentication-mode command to configure one area of OSPF to support the authentication attribute.

Use the undo authentication-mode command to cancel the authentication attribute of this area.

By default, an area does not support authentication attribute.

All the routers in one area must use the same authentication mode (no authentication, simple text authentication, or MD5 cipher text authentication). If the mode of supporting authentication is configured, all routers on the same segment must use the same authentication key.

Use the ospf authentication-mode simple command to configure a simple text authentication key.

Use the ospf authentication-mode md5 command to configure the MD5 cipher text authentication key if the area is configured to support MD5 cipher text authentication mode.

Related command: ospf authentication-mode.

3.1.5 default cost

Syntax

default cost value

undo default cost

View

OSPF view

Parameter

value: Default routing cost of external route imported by OSPF, ranging from 0 to 16,777,214. By default, its value is 1.

Description

Use the default cost command to configure the default cost for OSPF to import external routes.

Use the undo default cost command to restore the default routing cost of external routes to its default value.

Since OSPF can import external routing information and propagate the information to the entire autonomous system, routing cost of external routes can influence route selection and calculation. Therefore, it is necessary to specify the default routing cost for the protocol to import external routes.

Example

# Specify the default routing cost for OSPF to import external routes as 10.

Parameter

always: Generates an ase lsa describing the default route and advertises it if the local router is not configured with the default route. If this keyword is not provided, the local router must be configured with the default route before it can import the ase lsa, which generates the default route.

cost value: Specifies the cost value of this ase lsa. The value of value ranges from 0 to 16777214 and defaults to 1.

type type-value: Specifies the cost type of this ase lsa. The value of type-value ranges from 1 to 2 and defaults 2.

route-policy route-policy-name: If the default route matches the route-policy specified by route-policy-name, the route-policy will affect the value in ase lsa. The route-policy-name argument is a string containing 1 to 19 characters.

Description

Use the default-route-advertise command to import the default route to OSPF route area.

Use the undo default-route-advertise command to cancel the import of the default route.

By default, OSPF does not import the default route.

The import-route command cannot import the default route. To import the default route to the route area, the default-route-advertise command must be used. If the local router is not configured with the default route, the keyword always should be specified so that ase lsa of the default route is generated.

Related command: import-route.

Example

# The ase lsa of the default route is generated only if the local router has the default route.

3.1.25 filter-policy export

Syntax

filter-policy { acl-number | ip-prefix ip-prefix-name } export [ routing-protocol ]

undo filter-policy { acl-number | ip-prefix ip-prefix-name} export [ routing-protocol ]

View

OSPF view

Parameter

acl-number: Basic or advanced ACL number.

ip-prefix-name: Name of the address prefix list.

routing-protocol: Routing protocol advertising the routing information. At present, it can be direct, rip, or static.

Description

Use the filter-policy export command to configure the rule for filtering the advertised routing information by OSPF.

Use the undo filter-policy export command to cancel the filtering rule configured.

By default, no filtering of the advertised routing information is performed.

In some cases, it may be required that only the routing information meeting some conditions can be advertised. You can use the filter-policy command to set the filtering conditions for the routing information to be advertised. Only the routing information passing the filtration can be advertised.

This command affects the external routes imported (with the import-route command) by OSPF. If the routing-protocol argument is specified, this command filters only the imported routes generated by the specified protocol, not affecting the routes generated by any other protocol. If the routing-protocol argument is not specified, the imported routes generated by any protocol will be filtered.

Related command: acl, ip ip-prefix.

View

OSPF view

Parameter

acl-number: Basic or advanced Access control list used for filtering the destination addresses of the routing information.

ip-prefix-name: Name of the address prefix list used for filtering the destination addresses of the routing information.

gateway ip-prefix-name: Specifies the name of the address prefix list used for filtering the addresses of the neighbor routers advertising the routing information.

Description

Use the filter-policy import command to configure the OSPF rules for filtering the routing information received.

Use the undo filter-policy import command to cancel the filtering of the routing information received.

By default, no filtering of the received routing information is performed.

In some cases, it may be required that only the routing information meeting some conditions can be received. You can use the filter-policy command to set the filtering conditions for the routing information to be received. Only the routing information passing the filter can be received.

The filter-policy import command filters the routes calculated by OSPF. Only the routes passing the filter can be added to the routing table. The routes can be filtered based on next hop and destination address.

OSPF is a dynamic routing protocol based on link state, with routing information hidden in LSAs. Therefore, OSPF cannot filter any advertised or received LSA. This command is used much less in OSPF than in distance-vector routing protocols.

default-route-advertise: Imports the default route to the NSSA area.

no-import-route: Specifies not to import route to the NSSA area.

no-summary: An ABR is disabled from transmitting summary_net LSAs to the NSSA area.

Description

Use the nssa command to configure an OSPF area as an NSSA area.

Use the undo nssa command to cancel the function.

By default, no NSSA area is configured.

For all the routers connected to the NSSA area, the nssa command must be used to configure the area as the NSSA attribute.

The default-route-advertise argument is used to generate the default type-7 LSA. No matter whether the route 0.0.0.0 exists in the routing table on the ABR, the type-7 LSA default route will always be generated. The type-7 LSA default route is generated only when the route 0.0.0.0 exists in the routing table on the ASBR.

On the ASBR, if the no-import-route argument is provided, the external route imported by OSPF with the import-route command will not be advertised to NSSA area.

Syntax

ospf network-type { broadcast | nbma | p2mp | p2p }

undo ospf network-type

View

Interface view

Parameter

broadcast: Changes the interface network type to broadcast.

nbma: Changes the interface network type to NBMA.

p2mp: Changes the interface network type to point-to-multipoint.

p2p: Changes the interface network type to point-to-point.

Description

Use the ospf network-type command to configure the network type of OSPF interface.

Use the undo ospf network-type command to restore the default network type of the OSPF interface.

OSPF divides networks into four types based on link layer protocol:

l Broadcast: If Ethernet or FDDI is adopted, OSPF defaults the network type to broadcast.

l Non-Broadcast Multi-access (nbma): If Frame Relay, ATM, HDLC or X.25 is adopted, OSPF defaults the network type to NBMA.

l Point-to-Multipoint (p2mp): OSPF will not default the network type of any link layer protocol to p2mp. The general undertaking is to change a partially connected NBMA network to p2mp network if the NBMA network is not fully-meshed.

l Point-to-point (p2p): If PPP, LAPB or POS is adopted, OSPF defaults the network type to p2p.

If there is any router not supporting multicast addresses on a broadcast network, the network type of the interface can be changed to NBMA. Alternatively, the network type of the interface can be changed from NBMA to broadcast.

For a non-broadcast multi-accessible network to be of NBMA type, any two routers in the network must be directly reachable to each other through a virtual circuit. In other words, the network must be fully-meshed.

For a network not meeting this condition, the network type of the interface must be changed to point-to-multipoint. In this way, routing information can be exchanged between two routers not directly reachable to each other through another router that is directly reachable to the two routers.

If only two routers run OSPF in the same network segment, the network type of the interface can also be changed to point-to-point.

Note that you must use the peer command to configure the peer if the network type of the interface is NBMA or manually changed to NBMA with the ospf network-type command.

Related command: ospf dr-priority.

Parameter

seconds: Dead interval of the OSPF neighbor. It is in seconds and ranges from 1 to 65535.

Description

Use the ospf timer dead command to configure the dead interval of the OSPF peer.

Use the undo ospf timer dead command to restore the default value of the dead interval of the peer.

By default, the dead interval is 40 seconds for the OSPF peers of p2p and broadcast interfaces and is 120 seconds for those of p2mp and nbma interfaces.

The dead interval of OSPF peers means that, within this interval, if no Hello message is received from the peer, the peer will be considered to be invalid. The value of dead seconds should be at least four times of that of the Hello seconds. The dead seconds for the routers on the same network segment must be identical.

Related command: ospf timer hello.

Description

Use the ospf timer poll command to configure the poll Hello packet interval on NBMA and p2mp network.

Use the undo ospf timer poll command to restore the default poll interval.

On an NBMA or p2mp network, if a neighbor becomes invalid, Hello packet will be transmitted at the interval of poll seconds. You can configure the poll seconds to specify how often the interface transmits Hello packet before it establishes adjacency with the adjacent router. Poll seconds should be no less than 3 times of Hello.

Parameter

interval: Interval, in seconds, for retransmitting LSA on an interface. It ranges from 1 to 3600 and defaults to 5.

Description

Use the ospf timer retransmit command to configure the interval for LSA retransmission on an interface.

Use the undo ospf timer retransmit command to restore the default interval value for LSA retransmission on the interface.

If a router running OSPF transmits a "link state advertisement" (LSA) to the peer, it needs to wait for the acknowledgement packet from the peer. If no acknowledgement is received from the peer within the LSA retransmission interval, this LSA will be retransmitted.

The LSA retransmit between adjacent routers should not be set too short; otherwise, unexpected retransmission will occur (See RFC2328).

By default, the interface is enabled to transmit OSPF packet.

To prevent the router on some network from receiving the OSPF routing information, you can use this command to disable this interface from transmitting OSPF packet. On the switch, this command can be used to enable/disable OSPF packet transmission through the specified VLAN interface.

Example

# Disable interface Vlan-interface 20 from transmitting OSPF packet.

Description

Use the snmp-agent trap enable ospf command to enable the OSPF TRAP function.

Use the undo snmp-agent trap enable ospf command to disable the OSPF TRAP function.

This command does not apply to the OSPF processes that are started after the command is executed.

By default, the switch does not send TRAP packets in case of OSPF anomalies.

For detailed configuration of SNMP TRAP, refer to section "System Management" in this manual.

Example

# Enable the TRAP function for OSPF process 100.

3.1.50 spf-schedule-interval

Syntax

spf-schedule-interval interval

undo spf-schedule-interval

View

OSPF view

Parameter

interval: SPF calculation interval of OSPF, in seconds. It ranges from 1 to 10 and defaults to 5.

Description

Use the spf-schedule-interval command to configure the route calculation interval of OSPF.

Use the undo spf-schedule-interval command to restore the default setting.

According to the Link State Database (LSDB), the router running OSPF can calculate the shortest path tree taking itself as the root and determine the next hop to the destination network according to the shortest path tree. Adjusting SPF calculation interval restrains frequent network changes, which may occupy too many bandwidth resources and router resources.

Example

# Set the OSPF route calculation interval of H3C to 6 seconds.

Parameter

no-summary: Disables an ABR from transmitting Summary LSAs to the STUB area.

Description

Use the stub command to configure the type of an OSPF area as "stub".

Use the undo stub command to cancel the settings.

By default, no area is set to be the STUB area.

If the router is an ABR, it will send a default route to the connected stub area . Use the default-cost command to configure the default route cost. In addition, you can specify the no-summary argument in the stub command to disable the receiving of type-3 LSAs by the stub area connected to the ABR.

Related command: default-cost.

3.1.52 vlink-peer

Syntax

undo vlink-peer router-id

View

OSPF Area view

Parameter

route-id: Router ID of virtual link peer.

hello seconds: Specifies the interval, in seconds, at which the router transmits hello packet. It ranges from 1 to 8192 and defaults to 10. This value must equal the hello seconds value of the router virtually linked to the interface.

retransmit seconds: Specifies the interval, in seconds, for retransmitting the LSA packets on an interface. It ranges from 1 to 3600 and defaults to 5.

trans-delay seconds: Specifies the delay, in seconds, for transmitting LSA packets on an interface. It ranges from 1 to 3600 and defaults to 1.

dead seconds: Specifies the interval, in seconds, of death timer. It ranges from 1 to 8192 and defaults to 40. This value must equal the dead seconds of the router virtually linked to it and must be at least four times of the hello seconds.

simple password: Specifies the simple text authentication password, which contains up to eight characters, of the interface. This value must equal the authentication key of the virtually linked peer.

keyid: MD5 authentication key ID. It ranges from 1 to 255. It must be equal to the authentication key ID of the virtually linked peer.

key: MD5 authentication key. If you use simple text authentication key, you can input a string containing 1 to 16 characters. When you use the display current-configuration command to display system information, the MD5 authentication key is displayed in the form of cipher text with a length of 24 characters. Inputting the key in the form of cipher text with a length of 24 characters is also supported.

Description

Use the vlink-peer command to create and configure a virtual link.

Use the undo vlink-peer command to cancel an existing virtual link.

According to RFC2328, an OSPF area must be connected to the backbone network. You can use the vlink-peer command to keep the connectivity. Virtual link can be regarded as a common interface that uses OSPF because the principle for configuring the parameters such as hello, retransmit, and trans-delay on it is similar.

Note that, when configuring virtual link authentication, you use the authentication-mode command to specify the authentication mode as MD5 cipher text or simple text on the backbone network.

Related command: authentication-mode, display ospf.

Example

# Create a virtual link to 10.110.0.3 and use the MD5 cipher authentication mode.

undo ip ip-prefix ip-prefix-name [ index index-number | permit | deny ]

View

System view

Parameter

ip-prefix-name: Name of address prefix list. It identifies an address prefix list uniquely.

index-number: Identifier of an item in the prefix address list. The item with a smaller index-number will be tested first.

permit: Specifies the match mode of the defined address prefix list items as permit mode. If the permit mode is specified and the IP address to be filtered is in the ip-prefix range specified by the item, the item is filtered through and the next item is not tested. If the IP address to be filtered is not in the ip-prefix range specified by the item, the next item is tested

deny: Specifies the match mode of the defined address prefix list items as deny mode. If the deny mode is specified and the IP address to be filtered is in the ip-prefix range specified by the item, the item is not filtered through and the next item is not tested; otherwise, the next item is tested.

network: IP address prefix range (IP address).

len: IP address prefix range (mask length).

greater-equal, less-equal: Address prefix range [greater-equal, less-equal] to be matched after the address prefix network len has been matched. The meaning of greater-equal is "greater than or equal to" , and the meaning of less-equal is "less than or equal to". The range is len <= greater-equal <= less-equal <= 32. When only greater-equal is used, it denotes the prefix range [greater-equal, 32]. When only less-equal is used, it denotes the prefix range [len, less-equal].

Description

Use the ip ip-prefix command to configure an address prefix list or one of its items. Use the undo ip ip-prefix command to delete an address prefix list or one of its items.

An address prefix list is used for IP address filtering. An address prefix list may contain several items, and each item specifies one address prefix range. The inter-item filtering relation is "OR". That is, passing an item means filtering through this address prefix list. Not filtering through any item means not filtering through this prefix address list.

The address prefix range may contain two parts, which are determined by len and [greater-equal, less-equal], respectively. If the prefix ranges of these two parts are both specified, the IP to be filtered must match the prefix ranges of these two parts.

If you specify network len as 0.0.0.0 0, it matches the default route only.

To match all the routes, use 0.0.0.0 0 less-equal 32.

Example

# Define an ip-prefix named p1 to permit only the routes whose mask lengths are 17 or 18 on network segment 10.0.192.0/8 to pass.

4.1.11 route-policy

Syntax

route-policy route-policy-name { permit | deny } node node-number

undo route-policy route-policy-name [ permit | deny | node node-number ]

View

System view

Parameter

route-policy-name: Name of the Route-policy that identifies a Route-policy uniquely.

permit: Specifies the match mode of the defined Route-policy node as permit mode. When a route entry meets all the if-match clauses of the node, the entry is permitted to filter through the node and the apply clause of the node will be performed. If a route entry does not meet the if-match clause of the node, the next node of the route-policy will be tested.

deny: Specifies the match mode of the defined Route-policy node as deny mode. When a route entry meets all the if-match clauses of the node, the entry is prohibited from filtering through the node and the next node will not be tested.

node: Specifies the node of the route policy.

node-number: Index of the node in the route-policy. When this route-policy is used for routing information filter, the node with smaller node-number will be matched first.

Description

Use the route-policy command to enter the Route-policy view.

Use the undo route-policy command to delete the created Route-policy.

By default, no Route-policy is defined.

Route-policy is used for route information filter. A Route-policy comprises some nodes and each node comprises some if-match clauses and apply clauses.

An if-match clause defines the match rules of this node. An apply clause defines the actions after filtering through this node. The filtering relationship between the if-match clauses of the node is "and". That is, all if-match clauses of the node must be met.

The filtering relation between Route-policy nodes is "OR". That is, filtering through one node means filtering through this Route-policy. If the information does not filter through any node, it cannot filter through this Route-policy.

Related command: if-match interface, if-match acl, if-match ip-prefix, if-match ip next-hop, if-match cost, if-match tag, apply cost, and apply tag.

Example

# Configure Route-policy policy1, with the node number of 10 and the match mode of permit, and enter Route policy view.

5.1.3 memory

Syntax

memory { safety safety-value | limit limit-value }*

undo memory [ safety | limit ]

View

System view

Parameter

safety-value: Safety free memory of the switch , in Mbytes. Its value range depends on the free memory of the current switch. This value defaults to 5.

limit-value: Lower limit of the switch free memory, in Mbytes. Its value range depends on the free memory of the current switch. This value defaults to 4.

Description

Use the memory limit limit-value command to configure the lower limit of the switch free memory.

When the free memory of the switch is less than the limit-value, all the routing protocol connections will be disconnected forcibly.

Use the memory safety safety-value command to configure the safety value of the switch free memory.

If you use the memory auto-establish enable command (the default configuration), the routing protocol connection that is forcibly disconnected automatically recovers when the free memory of the switch reaches the safety-value.

Use the memory safety safety-value limit limit-value command to change both the safety value and lower limit of the switch free memory.

Use the undo memory command to restore the default safety value and lower limit of the switch free memory.

Related command: memory auto-establish disable, memory auto-establish enable, and display memory limit.

& Note:

When you configure the memory limit command, the safety-value argument in the command must be greater than the limit-value argument; otherwise, the configuration will fail.

Example

# Set the lower limit of the switch free memory to 1 MB and the safety value to 3 MB.

<H3C> system-view

System View: return to User View with Ctrl+Z.

5.1.4 memory auto-establish disable

Syntax

memory auto-establish disable

View

System view

Parameter

None

Description

Use the memory auto-establish disable command to disable the automatic restoration of routing protocol connection (even if the free memory recovers to a safety value).

By default, when the free memory of the switch recovers to a safety value, connections of all the routing protocols will always recover (when the free memory of the switch decreases to a lower limit, the connection will be disconnected forcibly).

After this command is used, connections of all the routing protocols will not recover when the free memory of the switch recovers to a safety value. In this case, you need to restart the routing protocol to recover the connections.

Use this command with caution.

Related command: memory auto-establish enable, memory { safety | limit }, display memory limit.
