undo ip route-static dest-address { mask | mask-length } [ next-hop-address | interface-type interface-number [ next-hop-address ] ] [ preference preference-value ]

View

System view

Parameters

dest-address: Destination IP address of the static route, in dotted decimal notation.

mask: Mast of the IP address, in dotted decimal notation.

mask-length: Mask length, in the range 0 to 32.

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

interface-type interface-number: Specifies the output interface by its type and number. If the output interface is a broadcast interface, such as an Ethernet interface, a virtual template or a VLAN interface, the next hop address must be specified.

preference preference-value : Specifies the preference of the static route, which is in the range of 1 to 255 and defaults to 60.

tag tag-value: Sets a tag value for the static route from 1 to 4294967295. The default is 0. Tags of routes are used in routing policies to control routing.

description description-text: Configures a description for the static route, which consists of 1 to 60 characters, including special characters like space, but excluding “?”.

track track-entry-number: Associates the static route with a track entry. Use the track-entry-number argument to specify a track entry number, in the range 1 to 1024.

Description

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

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

When configuring a unicast static route, note that:

1) If the destination IP address and the mask are both 0.0.0.0, the configured route is a default route. If routing table searching fails, the router will use the default route for packet forwarding.

2) Different route management policies can be implemented for different route preference configurations. For example, specifying the same preference for different routes to the same destination address enables load sharing, while specifying different preferences for these routes enables route backup.

3) When configuring a static route, you can specify the output interface or the next hop address based on the actual requirement. Note that the next hop address must not be the IP address of the local interface; otherwise, the route configuration will not take effect. For interfaces that support network address to link layer address resolution or point-to-point interfaces, you can specify the output interface or next hop address. When specifying the output interface, note that:

l For a NULL 0 interface, if the output interface has already been configured, there is no need to configure the next hop address.

l It is not recommended to specify a broadcast interface (such as VLAN interface) as the output interface for a static route, because a broadcast interface may have multiple next hops. If you have to do so, you must specify the corresponding next hop of the interface at the same time.

Related commands: display ip routing-table, ip route-static default-preference.

& Note:

l The static route does not take effect if you specify its next hop address first and then configure the address as the IP address of a local interface, such as VLAN interface.

l To configure track monitoring for an existing static route, simply associate the static route with a track entry. For a non-existent static route, configure it and associate it with a Track entry.

l If a static route needs route recursion, the associated track entry must monitor the nexthop of the recursive route instead of that of the static route; otherwise, a valid route may be mistakenly considered invalid.

Examples

# Configure a static route, whose destination address is 1.1.1.1/24, next hop address is 2.2.2.2, tag value is 45, and description information is for internet & intranet.

2.1 RIP Configuration Commands

2.1.1 checkzero

Syntax

checkzero

undo checkzero

View

RIP view

Parameters

None

Description

Use the checkzero command to enable the zero field check on RIPv1 messages.

Use the undo checkzero command to disable the zero field check.

The zero field check is enabled by default.

After the zero field check is enabled, the router discards RIPv1 messages in which zero fields are non-zero. If all messages are trusty, you can disable this feature to spare the processing time of the CPU.

Examples

# Disable the zero field check on RIPv1 messages for RIP process 100.

<Sysname> system-view

[Sysname] rip 100

[Sysname-rip-100] undo checkzero

2.1.2 default cost

Syntax

default cost value

undo default cost

View

RIP view

Parameters

value: Default metric of redistributed routes, in the range of 0 to 16.

Description

Use the default cost command to configure the default metric for redistributed routes.

Use the undo default cost command to restore the default.

By default, the default metric of redistributed routes is 0.

When you use the import-route command to redistribute routes from other protocols without specifying a metric, the metric specified by the default cost command applies.

Related command: import-route.

Examples

# Set the default metric for redistributed routes to 3.

<Sysname> system-view

[Sysname] rip 100

[Sysname-rip-100] default cost 3

2.1.3 default-route originate

Syntax

default-route originate cost value

undo default-route originate

View

Parameters

value: Cost of the default route, in the range of 1 to 15.

Description

Use the default-route originate cost command to advertise a default route with the specified metric to RIP neighbors.

Use the undo default-route originate command to disable the sending of a default route.

By default, no default route is sent to RIP neighbors.

The RIP router with this feature configured will not receive any default routes from RIP neighbors.

Examples

# Send a default route with a metric of 2 to RIP neighbors.

<Sysname> system-view

[Sysname] rip 100

[Sysname-rip-100] default-route originate cost 2

View

RIP view

Parameters

None

Description

Use the host-route command to enable host route reception.

Use the undo host-route command to disable host route reception.

By default, receiving host routes is enabled.

In some cases, a router may receive many host routes from the same network segment. These routes are not helpful for routing and occupy a large amount of network resources. You can use the undo host-route command to disable receiving of host routes.

& Note:

RIPv2 can be disabled from receiving host routes, but RIPv1 cannot.

Examples

# Disable RIP from receiving host routes.

undo import-route protocol

View

RIP view

Parameters

protocol: Specify a routing protocol from which to redistribute routes, currently including direct and static.

cost: Cost for redistributed routes, in the range of 0 to 16. If cost is not specified, the default cost specified by the default cost command applies.

tag: Tag marking redistributed routes, in the range of 0 to 65,535. The default is 0.

route-policy route-policy-name: Specifies a routing policy with 1 to 19 characters.

Description

Use the import-route command to enable route redistribution from another routing protocol.

Use the undo import-route command to disable route redistribution.

By default, RIP does not redistribute routes from other routing protocols.

l You can specify a routing policy using keyword route-policy to redistribute only the specified routes.

l You can configure a cost for redistributed routes using keyword cost.

l You can configure a tag value for redistributed routes using keyword tag.

Related commands: default cost.

Examples

# Redistribute static routes, and set the cost to 4.

2.1.12 network

Syntax

network network-address

undo network network-address

View

RIP view

Parameters

network-address: IP address of a network segment, which can be the IP network address of any interface.

Description

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

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

RIP runs only on the interfaces attached to the specified network. For an interface not on the specified network, RIP neither receives/sends routes on it nor forwards interface route through it. Therefore, you need to specify the network after enabling RIP to validate RIP on a specific interface.

Use the network 0.0.0.0 command to enable RIP on all interfaces.

RIP is disabled on an interface by default.

Examples

# Enable RIP on the interface attached to the network 129.102.0.0.

<Sysname> system-view

[Sysname] rip 100

[Sysname-rip-100] network 129.102.0.0

2.1.13 peer

Parameters

ip-address: IP address of a RIP neighbor, in dotted decimal format.

Description

Use the peer command to specify the IP address of a neighbor in the non-broadcast multi-access (NBMA) network, where routing updates destined to the peer are unicast, rather than multicast or broadcast.

Use the undo peer command to remove the IP address of a neighbor.

By default, no neighbor is specified.

Note: you need not use the peer ip-address command when the neighbor is directly connected; otherwise the neighbor may receive both the unicast and multicast (or broadcast) of the same routing information.

Examples

# Specify to send unicast updates to peer 202.38.165.1.

2.1.19 rip metricin

Syntax

rip metricin [ route-policy route-policy-name ] value

undo rip metricin

View

Interface view

Parameters

route-policy route-policy-name: Specifies the name of a routing policy used to add an additional metric for the routes matching it. The name is a string of 1 to 19 characters.

value: Additional metric added to received routes, in the range of 0 to 16.

Description

Use the rip metricin command to add a metric to the received routes.

Use the undo rip metricin command to restore the default.

By default, the additional metric of a received route is 0.

When a valid RIP route is received, the system adds a metric to it and then installs it into the routing table. Therefore, the metric of routes received on the configured interface is increased.

If a routing policy is referenced with the route-policy keyword:

l Routes matching the policy is added with the metric specified in the apply cost command configured in the policy, while routes not matching it is added with the metric specified in the rip metricout command. Note that, the rip metricout command does not support the + or – keyword (used to add or reduce a metric) specified in the apply cost command. For details about the apply cost command, refer to Routing Policy Commands .

l If the apply cost command is not configured in the policy, all the advertised routes is added with the metric specified in the rip metricout command.

Related commands: rip metricout.

Examples

# Configure VLAN-interface 10 to add a metric of 6 for incoming route 1.0.0.0/8 and to add a metric of 2 for other incoming routes.

Use the undo rip metricout command to restore the default.

By default, the additional metric for sent routes is 1.

Before a RIP route is sent, a metric will be added to it. Therefore, when the metric is configured on an interface, the metric of RIP routes sent on the interface will be increased.

If a routing policy is referenced with the route-policy keyword:

l If the apply cost command is not configured in the policy, all the advertised routes is added with the metric specified in the rip metricout command.

Related commands: rip metricin.

broadcast: Sends RIPv2 messages in broadcast mode.

multicast: Sends RIPv2 messages in multicast mode.

Description

Use the rip version command to specify a RIP version for the interface.

Use the undo rip version command to remove the specified RIP version.

By default, no RIP version is configured for an interface, which uses the global RIP version. If the global RIP version is not configured, the interface can only send RIPv1 broadcasts and can receive RIPv1 broadcasts and unicasts, and RIPv2 broadcasts, multicasts and unicasts.

If RIPv2 is specified with no sending mode configured, RIPv2 messages will be sent in multicast mode.

When RIPv1 runs on an interface, the interface will:

l Send RIPv1 broadcast messages

l Receive RIPv1 broadcast messages

l Receive RIPv1 unicast messages

When RIPv2 runs on the interface in broadcast mode, the interface will:

l Send RIPv2 broadcast messages

l Receive RIPv1 broadcast messages

l Receive RIPv1 unicast messages

l Receive RIPv2 broadcast messages

l Receive RIPv2 multicast messages

l Receive RIPv2 unicast messages

2.1.28 timers

Syntax

timers { garbage-collect garbage-collect-value | suppress suppress-value | timeout timeout-value | update update-value }*

undo timers { garbage-collect | suppress | timeout | update } *

View

RIP view

Parameters

garbage-collect-value: Garbage-collect timer time in seconds, in the range of 1 to 3600.

suppress-value: Suppress timer time in seconds, in the range of 0 to 3600.

timeout-value: Timeout timer time in seconds, in the range of 1 to 3600.

update-value: Update timer time in seconds, in the range of 1 to 3600.

Description

Use the timers command to configure RIP timers. By adjusting RIP timers, you can improve network performance.

Use the undo timers command to restore the default.

By default, the garbage-collect timer is 120 seconds, the suppress timer 120 seconds, the timeout timer 180 seconds, and the update timer 30 seconds.

RIP is controlled by the above four timers.

l The update timer defines the interval between routing updates.

l The timeout timer defines the route aging time. If no routing update related to a route is received after the aging time, the metric of the route is set to 16 in the routing table.

l The suppress timer defines how long a RIP route stays in the suppressed state. When the metric of a route is 16, the route enters the suppressed state. In the suppressed state, only routes which come from the same neighbor and whose metric is less than 16 will be received by the router to replace unreachable routes.

l The garbage-collect timer defines the interval from when the metric of a route becomes 16 to when it is deleted from the routing table. During the Garbage-Collect timer length, RIP advertises the route with the routing metric set to 16. If no routing update is announced for that route after the Garbage-Collect timer expires, the route will be deleted from the routing table.

Note that:

l Generally, you are not recommended to change the default values of these timers.

l The time lengths of these timers must be kept consistent on all routers and access servers in the network.

Examples

# Specifies the update, timeout, suppress, and garbage-collect timers as 5, 15, 15 and 30 respectively.

<Sysname> system-view

[Sysname] rip 100

[Sysname-rip-100] timers update 5

undo version

View

RIP view

Parameters

1: Specifies the RIP version as RIPv1.

2: Specifies the RIP version as RIPv2. RIPv2 messages are multicast.

Description

Use the version command to specify a global RIP version.

Use the undo version command to remove the configured global RIP version.

By default, if an interface has a RIP version specified, the RIP version takes effect; if it has no RIP version specified, it can send RIPv1 broadcasts, and receive RIPv1 broadcasts, RIPv1 unicasts, RIPv2 broadcasts, RIPv2 multicasts, and RIPv2 unicasts.

Note that:

l If an interface has an RIP version specified, the RIP version takes precedence over the global RIP version.

l If no RIP version is specified for the interface and the global version is RIPv1, the interface inherits RIPv1, and it can send RIPv1 broadcasts, and receive RIPv1 broadcasts and unicasts.

l If no RIP version is specified for the interface and the global version is RIPv2, the interface operates in the RIPv2 muticast mode, and it can send RIPv2 multicasts, and receive RIPv2 broadcasts, multicasts and unicasts.

Examples

# Specify RIPv2 as the global RIP version.

3.2.6 ip ip-prefix

Syntax

ip ip-prefix ip-prefix-name [ index index-number ] { permit | deny } ip-address mask-length [ greater-equal min-mask-length ] [ less-equal max-mask-length ]

undo ip ip-prefix ip-prefix-name [ index index-number ]

View

System view

Parameters

ip-prefix-name: IPv4 prefix list name, a string of 1 to 19 characters.

index-number: Index number, in the range 1 to 65535, for uniquely specifying an item of the IPv4 prefix list. The index with a smaller number is tested first.

permit: Specifies the matching mode for the IPv4 prefix list as permit, that is, when a route to be filtered is in the range of the IPv4 prefix list, the route passes the IPv4 prefix list without needing to enter the next item for testing. If the route to be filtered is not in the prefix range, it will enter the next item test.

deny: Specifies the matching mode for the IPv4 prefix list as deny, that is, when a route to be filtered is in the IPv4 prefix list range, the route neither passes the filter nor enters the next node for testing. If not in the range, the route will enter the next item test.

ip-address mask-length: Specifies an IPv4 address prefix and mask length. The mask-length is in the range 0 to 32.

min-mask-length, max-mask-length: Specifies the range for prefix if the IPv4 address and prefix length are matched. greater-equal means “greater than or equal to” and less-equal means “less than or equal to”. The range relation is mask-length <= min-mask-length <= max-mask-length <= 32. If only min-mask-length is specified, the prefix length range is [ min-mask-length, 32 ]. If only max-mask-length is specified, the prefix length range is [mask-length, max-mask-length ]. If both min-mask-length and max-mask-length are specified, the prefix length range is [ min-mask-length, max-mask-length ].

Description

Use the ip ip-prefix command to configure an IPv4 prefix list item.

Use the undo ip ip-prefix command to remove an IPv4 prefix list or an item.

No IPv4 prefix list is configured by default.

An IPv4 prefix list is used to filter IPv4 addresses. It may have multiple items, each of which specifies a range of IPv4 prefix. The filtering relation among items is logic OR, namely, passing any item means the IPv4 prefix list is passed. If no item is passed, the IP prefix list cannot be passed.

The IP prefix range is determined by mask-length and [ min-mask-length, max-mask-length ]. If both mask-length and [ min-mask-length, max-mask-length ] are specified, then the IP address to be filtered must satisfy both of them.

If ip-address mask-length is specified as 0.0.0.0 0, then only the default route is matched.

With the keyword and argument combination ip-address mask-length less-equal specified as 0.0.0.0 less-equal 32, the command matches all the routes.

Examples

# Create a routing policy named policy1 with node 10, matching mode as permit. Define an IP prefix list named p1 to permit only the routes in the network segment 10.0.192.0/8 and with mask length 17 or 18.
