prefix-length: Prefix length of the destination IPv6 address, in the range of 0 to 128. This argument specifies the number of consecutive 1s of the prefix, which defines the network ID.

not-advertise: Specifies not to advertise the summary IPv6 route.

Description

Use the abr-summary command to configure an IPv6 summary route on an area border router.

Use the undo abr-summary command to remove an IPv6 summary route. Then the summarized routes are advertised.

By default, no route summarization is available on an ABR.

You can use this command only on an ABR to configure a summary route for the area. The ABR advertises only the summary route to other areas. Multiple contiguous networks may be available in an area, where you can summarize them with one route for advertisement.

Examples

# Summarize networks 2000:1:1:1::/64 and 2000:1:1:2::/64 in Area 1 with 2000:1:1::/48.

Parameters

area-id: ID of an area, a decimal integer (in the range of 0 to 4294967295 and changed to IPv4 address format by the system) or an IPv4 address.

Description

Use the area command to enter OSPFv3 area view.

NOTE:

The undo form of the command is not available. An area is removed automatically if there is no configuration and no interface is up in the area.

Examples

# Enter OSPFv3 Area 0 view.

Parameters

value: Bandwidth reference value for link cost calculation, in the range of 1 to 2147483648 Mbps.

Description

Use the bandwidth-reference command to specify a reference bandwidth value for link cost calculation.

Use the undo bandwidth-reference command to restore the default value.

The default value is 100 Mbps.

You can configure an OSPFv3 cost for an interface with one of the following two methods:

· Configure the cost value in interface view.

· Configure a bandwidth reference value, and OSPFv3 computes the cost automatically based on the bandwidth reference value: Interface OSPFv3 cost = Bandwidth reference value/Interface bandwidth. If the calculated cost is greater than 65535, the value of 65535 is used.

If no cost value is configured for an interface, OSPFv3 automatically computes the interface cost value.

Examples

# Specify the reference bandwidth value as 1000 Mbps.

Parameters

value: Specifies a default cost for redistributed routes, in the range of 1 to 16777214.

Description

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

Use the undo default cost command to restore the default.

By default, the default cost is 1.

You need to configure the default cost value for redistributed routes to advertise them throughout the whole AS.

If multiple OSPFv3 processes are available, use of this command takes effect for the current process only.

Examples

# Specify the default cost for redistributed routes as 10.

2: System level

Parameters

value: Specifies a cost for the default route advertised to the stub area, in the range of 0 to 65535. The default is 1.

Description

Use the default-cost command to specify the cost of the default route to be advertised to the stub area.

Use the undo-default-cost command to restore the default value.

Use of this command is only available on the ABR that is connected to a stub area.

You have two commands to configure a stub area: stub, defaulted-cost. You need to use the stub command on routers connected to a stub area to configure the area as stub.

If multiple OSPFv3 processes are running, use of this command takes effect only for the current process.

Related commands: stub.

Examples

# Configure Area1 as a stub area, and specify the cost of the default route advertised to the stub area as 60.

<Sysname> system-view

Default level

2: System level

Parameters

always: Generates a default route in an ASE LSA into the OSPF routing domain regardless of whether the default route exists in the routing table. Without this keyword, the command can distribute a default route in a Type-5 LSA into the OSPF routing domain only when the default route exists in the routing table.

cost value: Specifies a cost for the default route, in the range of 0 to 16777214. The default is 1.

route-policy route-policy-name: Specifies a routing policy, the name of which is a case-sensitive string of 1 to 63 characters.

type type: Specifies a type for the ASE LSA: 1 or 2. The default is 2.

Description

Use the default-route-advertise command to generate a default route into the OSPF routing domain.

Use the undo default-route-advertise command to disable OSPF from redistributing a default route.

By default, no default route is redistributed.

Using the import-route command cannot redistribute a default route. To do so, you need to use the default-route-advertise command. If no default route exists in the router's routing table, use the default-route-advertise always command to generate a default route in a Type-5 LSA.

You can reference a routing policy to set the cost and type of the default route:

· The router advertises the default route only when it passes the routing policy.

· The default route passing the routing policy uses the cost set by the apply cost clause, and the type set by the apply cost-type clause in the routing policy.

· The default route cost’s priority from high to low is: the cost set by the apply cost clause in the routing policy, the one set by the default-route-advertise command and the one set by the default cost command.

· The default route type’s priority from high to low is: the type set by the apply cost-type clause in the routing policy, and the one set by the default-route-advertise command.

· If the always keyword is included, the default route is advertised regardless of whether it passes the routing policy and uses the cost and type specified by the apply cost, apply cost-type clauses in the first node of the routing policy.

Related commands: import-route.

Parameters

policy-name: IPsec policy name, a string of 1 to 15 characters.

Description

Use the enable ipsec-policy command to apply an IPsec policy in the OSPFv3 area.

Use the undo enable ipsec-policy command to remove the IPsec policy from the OSPFv3 area.

By default, no IPsec policy is applied in an area.

The IPsec policy to be applied must have been configured.

Default level

2: System level

Parameters

acl6-number: Specifies the ACL6 number, ranging from 2000 to 3999.

ipv6-prefix ipv6-prefix-name: Specifies the name of an IPv6 prefix list, a string of up to 19 characters.

bgp4+: Filters IPv6 BGP routes.

direct: Filters direct routes.

isisv6 process-id: Specifies to filter the routes of an IPv6 IS-IS process, which is in the range of 1 to 65535.

ospfv3 process-id: Specifies to filter the routes of an OSPFv3 process, which is in the range of 1 to 65535.

ripng process-id: Specifies to filter the routes of a RIPng process, which in the range of 1 to 65535.

static: Specifies to filter static routes.

Description

Use the filter-policy export command to filter redistributed routes.

Use the undo filter-policy export command to remove the configuration.

By default, OSPFv3 does not filter redistributed routes.

If no protocol is specified, all redistributed routes will be filtered.

If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, the ACL should be configured with the rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix command to deny/permit a route with the specified destination, or with the rule [ rule-id ] { deny | permit } ipv6 source sour sour-prefix destination dest dest-prefix command to deny/permit a route with the specified destination and prefix. The source keyword specifies the destination address of a route while the destination keyword specifies the prefix of the route (the prefix must be valid; otherwise, the configuration is ineffective).

Using the filter-policy export command filters only routes redistributed by the import-route command. If the import-route command is not configured to redistribute routes from other protocols and other OSPFv3 processes, use of the filter-policy export command does not take effect.

Examples

# Filter all redistributed routes using IPv6 ACL 2001.

<Sysname> system-view

[Sysname] acl ipv6 number 2001

2: System level

Parameters

value: OSPFv3 cost of the interface, in the range of 1 to 65535.

instance-id: Instance ID of an interface, in the range of 0 to 255, which defaults to 0.

Description

Use the ospfv3 cost command to configure the OSPFv3 cost of the interface in an instance.

Use the undo ospfv3 cost command to restore the default OSPFv3 cost of the interface in an instance.

The default cost depends on the interface type: 1 for a VLAN interface; 0 for a loopback interface; computed according to the bandwidth for other interfaces with the formula: Interface OSPF cost = Bandwidth reference value (100 Mbps) ÷ Interface bandwidth (Mbps).

If the calculated cost is greater than 65535, the value of 65535 is used; if the calculated cost is smaller than 1, the value of 1 is used.

Parameters

seconds: Dead time in seconds, ranging from 1 to 65535.

instance-id: Instance ID of an interface, in the range of 0 to 255, which defaults to 0.

Description

Use the ospfv3 timer dead command to configure the OSPFv3 neighbor dead time for an interface that belongs to a specified instance.

Use the undo ospfv3 timer dead command to restore the default.

By default, the OSPFv3 neighbor dead time is 40 seconds for P2P and Broadcast interfaces, and is 120 seconds for P2MP and NBMA interfaces.

OSPFv3 neighbor dead time: if an interface receives no hello packet from a neighbor after dead time elapses, the interface will consider the neighbor dead.

The dead seconds value is at least four times the Hello seconds value and must be identical on interfaces attached to the same network segment.

Related commands: ospfv3 timer hello.

Examples

# Configure the OSPFv3 neighbor dead time as 80 seconds for VLAN-interface 10 in instance 1.

ospfv3 timer retransmit

Syntax

ospfv3 timer retransmit interval [ instance instance-id ]

undo ospfv3 timer retransmit [ interval ] [ instance instance-id ]

View

Interface view

Default level

2: System level

Parameters

interval: LSA retransmission interval in seconds, ranging from 1 to 65535.

instance-id: Instance ID of an interface, in the range of 0 to 255, which defaults to 0.

Description

Use the ospfv3 timer retransmit command to configure the LSA retransmission interval for an interface in an instance.

Use the undo ospfv3 timer retransmit command to restore the default.

The interval defaults to 5 seconds.

After sending a LSA to its neighbor, the switch waits for an acknowledgement. If receiving no acknowledgement after the LSA retransmission interval elapses, it will retransmit the LSA.

The LSA retransmission interval should not be too small for avoidance of unnecessary retransmissions.

Examples

# Configure the LSA retransmission interval on VLAN-interface 10 in instance 1 as 12 seconds.

<Sysname> system-view

[Sysname] interface vlan-interface 10

[Sysname-Vlan-interface10] ospfv3 timer retransmit 12 instance 1

View

Interface view

Default level

2: System level

Parameters

seconds: Transmission delay in seconds, ranging from 1 to 3600.

instance-id: Instance ID of an interface, in the range of 0 to 255, with the default as 0.

Description

Use the ospfv3 trans-delay command to configure the transmission delay for an interface with an instance ID.

Use the undo ospfv3 trans-delay command to restore the default.

The transmission delay defaults to 1s.

As LSAs are aged in the LSDB (incremented by 1 every second) but not aged on transmission, it is necessary to add a delay time to the age time before sending a LSA. This configuration is important for low-speed networks.

Examples

# Configure the transmission delay as 3 seconds for VLAN-interface 10 in instance 1.

<Sysname> system-view

View

OSPFv3 view

Default level

2: System level

Parameters

ase: Applies the preference to OSPFv3 external routes. If the keyword is not specified, the preference applies to OSPFv3 internal routes.

route-policy route-policy-name: References a routing policy to set preference for specific routes. The name is a case-sensitive string of 1 to 63 characters.

Preference: Preference of OSPFv3, in the range of 1 to 255.

Description

Use the preference command to specify a preference for OSPFv3 routes.

Use the undo preference command to restore the default.

By default, the preference for OSPFv3 internal routes is 10, and that for OSPFv3 external routes is 150.

The smaller the value is, the higher the preference is.

A router may run multiple routing protocols. Each protocol has a preference. When several routing protocols find multiple routes to the same destination, the route found by the protocol with the highest preference is selected.

Examples

# Set a preference of 150 for OSPFv3 routes.

<Sysname> system-view

2: System level

Parameters

router-id: 32-bit router ID, in IPv4 address format.

Description

Use the router-id command to configure the OSPFv3 router ID.

Use the undo router-id command to remove a configured router ID.

Router ID is the unique identifier of a switch running an OSPFv3 process in the AS. The OSPFv3 process cannot run without a Router ID.

Make sure that different processes have different Router IDs.

Related commands: ospfv3.

NOTE:

By configuring different router IDs for different processes, you can run multiple OSPFv3 processes on a router.

Examples

# Configure the Router ID as 10.1.1.3 for OSPFv3 process 1.

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] router-id 10.1.1.3

silent-interface (OSPFv3 view)

undo silent-interface { interface-type interface-number | all }

View

OSPFv3 view

Default level

2: System level

Parameters

interface-type interface-number: Interface type and number

all: Specifies all interfaces.

Description

Use the silent-interface command to disable the specified interface from receiving and sending OSPFv3 packets.

Use the undo silent-interface command to restore the default.

An interface is able to receive and send OSPFv3 packets by default.

Multiple processes can disable the same interface from receiving and sending OSPFv3 packets, but use of the silent-interface command takes effect only on interfaces enabled with the current process.

Examples

# Disable VLAN-interface 10 from receiving and sending OSPFv3 packets in OSPFv3 processes 100 and 200.

<Sysname> system-view

[Sysname] ospfv3 100

spf timers

Syntax

spf timers delay-interval hold-interval

undo spf timers

View

OSPFv3 view

Default level

2: System level

Parameters

delay-interval: Interval in seconds between when OSPFv3 receives a topology change and when it starts SPF calculation. in the range of 0 to 65535.

hold-interval: Hold interval in seconds between two consecutive SPF calculations, in the range of 0 to 65535.

Description

Use the spf timers command to configure the delay interval and hold interval for OSPFv3 SPF calculation.

Use the undo spf timers command to restore the default.

The delay interval and hold interval default to 5s and 10s.

An OSPFv3 router works out a shortest path tree with itself as root based on the LSDB, and decides on the next hop to a destination network according the tree. Adjusting the SPF calculation interval can restrain bandwidth and router resource from over consumption due to frequent network changes.

Setting both the delay-interval and hold-interval to 0 triggers an SPF calculation at once, improving the network convergence speed.

Examples

# Configure the delay interval and hold interval as 6 seconds for SPF calculation.

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] spf timers 6 6

stub (OSPFv3 area view)

Syntax

stub [ no-summary ]

undo stub

View

OSPFv3 area view

Default level

2: System level

Parameters

no-summary: This argument is only applicable to the ABR of a stub area. With this keyword configured, the ABR advertises only a default route in an Inter-Area-Prefix-LSA into the stub area. No AS-external-LSA, Inter-Area-Router-LSA, or other Inter-Area-Prefix-LSA is advertised in the area. The stub area of this kind is also known as a “totally stub area.”

Description

Use the stub command to configure an area as a stub area.

Use the undo stub command to remove the configuration.

By default, an area is not configured as a stub area.

When an area is configured as a stub area, all the routers attached to the area must be configured with the stub command.

Related commands: default-cost.

Examples

# Configure OSPFv3 area 1 as a stub area.

<Sysname> system-view

[Sysname] ospfv3 1

vlink-peer (OSPFv3 area view)

Syntax

undo vlink-peer router-id [ hello | retransmit | trans-delay | dead | ipsec-policy ] *

View

OSPFv3 area view

Default level

2: System level

Parameters

router-id: Router ID for a virtual link neighbor.

hello seconds: Specifies the interval in seconds for sending Hello packets, ranging from 1 to 8192, with the default as 10. This value must be equal to the hello seconds configured on the virtual link peer.

retransmit seconds: Specifies the interval in seconds for retransmitting LSA packets, ranging from 1 to 3600, with the default as 5.

trans-delay seconds: Specifies the delay interval in seconds for sending LSA packets, ranging from 1 to 3600, with the default as 1.

dead seconds: Specifies the neighbor dead time in seconds, ranging from 1 to 32768, with the default as 40. This value must be equal to the dead seconds configured on the virtual link peer, and at least four times the value of hello seconds.

instance Instance-id: Instance ID of an virtual link, in the range of 0 to 255, with the default as 0.

ipsec-policy policy-name: Applies an IPsec policy, the name of which is a string of 1 to 15 characters.

Description

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

Use the undo vlink-peer command to remove a virtual link.

For a non-backbone area without a direct connection to the backbone area or for a backbone area that cannot maintain connectivity, you can use the vlink-peer command to create logical links. A virtual link can be considered as an interface with OSPFv3 enabled, because parameters such as hello, dead, retransmit and trans-delay are configured in the similar way.

Both ends of a virtual link are ABRs that are configured with the vlink-peer command.

If you have enabled the GR capability for the current process, you cannot execute the vlink-peer command for the process.

Examples

# Create a virtual link to 10.110.0.3.

<Sysname> system-view

[Sysname] ospfv3 1
