prefix-length: Specifies the 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 abr-summary to configure an IPv6 summary route on an area border router.

Use undo abr-summary 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 might 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: Specifies an area by its ID, an IPv4 address or a decimal integer in the range of 0 to 4294967295 that is translated into an IPv4 address by the system.

Description

Use area to enter OSPFv3 area view.

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.

2: System level

Parameters

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

Description

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

Use undo bandwidth-reference 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 0 to 16777214.

Description

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

Use undo default cost 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 16777214. The default is 1.

Description

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

Use undo-default-cost to restore the default.

By default, the cost of the default route advertised to the stub area or NSSA area is specified by the default-cost command. For a stub area, the setting is the cost of the default route. For an NSSA area, the setting is the cost of the default Inter-Area-Prefix-LSA route.

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

Examples

# Configure Area 1 as a stub area, and specify the cost of the default route advertised to the stub area as 60.

<Sysname> system-view

[Sysname] ospfv3

[Sysname-ospfv3-1] area 1

Default level

2: System level

Parameters

always: Generates a default route in an ASE LSA into the OSPFv3 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 OSPFv3 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. Without this option, the default cost is specified by the default cost command.

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 default-route-advertise to generate a default route into the OSPFv3 routing domain.

Use undo default-route-advertise to disable OSPFv3 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 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: Specifies an IPsec policy by its name, a string of 1 to 15 characters.

Description

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

Use undo enable ipsec-policy 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 an IPv6 ACL by its number in the range of 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: Filters the routes of an IPv6 IS-IS process, which is in the range of 1 to 65535.

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

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

static: Filters static routes.

Description

Use filter-policy export to filter redistributed routes.

Use undo filter-policy export 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

[Sysname-acl6-basic-2000] rule permit source 2002:1:: 64

By default, the ABR or ASBR of an NSSA area advertises no default routes.

cost cost: Specifies the cost of the default route in an NSSA-external-LSA, in the range of 0 to 16777214.

type type: Specifies the type of the default route in an NSSA-external-LSA, in the range of 1 to 2. The default value is 2.

no-import-route: Usable only on an NSSA ABR that is also the ASBR of the OSPFv3 routing domain to disable redistributing routes in NSSA-external-LSAs into the NSSA area, making sure that routes can be correctly redistributed.

no-summary: Usable only on an NSSA ABR to advertise only a default route in an Inter-Area-Prefix-LSA into the NSSA area. No Inter-Area-Prefix-LSA is advertised in the area. Such an area is a totally NSSA area.

suppress-fa: Suppresses the forwarding address (FA) from being advertised in the translation of NSSA-external-LSAs to AS-external-LSAs.

translate-always: Specifies the NSSA ABR as a translator to translate NSSA-external-LSAs to AS-external-LSAs.

translate-never: Specifies the device not to be a translator.

translator-stability-interval value: Specifies the stability interval of the translator, during which the translator can maintain its translating capability after a device with a higher priority becomes a new translator. The value argument is the stability interval in the range of 0 to 900 seconds and defaults to 0 (which means the translator does not maintain its translating capability if a new translator arises).

Description

Use nssa to configure an area as an NSSA area.

Use undo nssa to restore the default.

By default, no area is configured as an NSSA area.

All routers attached to an NSSA area must be configured with the nssa command in area view.

With the default-route-advertise keyword configured, the default route cost is selected in the following sequence: the nssa command, the default-cost command in OSPFv3 area view, and the default-cost command in OSPFv3 view.

Examples

# Configure OSPFv3 area 1 as an NSSA area.

Parameters

interval: Specifies the LSA retransmission interval in seconds, in the range of 1 to 65535.

instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0.

Description

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

Use undo ospfv3 timer retransmit 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.

Parameters

seconds: Specifies the transmission delay in seconds, in the range of 1 to 3600.

instance-id: Specifies an instance by its ID in the range of 0 to 255. The default is 0.

Description

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

Use undo ospfv3 trans-delay to restore the default.

The transmission delay defaults to 1 second.

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.

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: Specifies the preference of OSPFv3, in the range of 1 to 255.

Description

Use preference to specify a preference for OSPFv3 routes.

Use undo preference 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 might 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.

Description

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

Use undo silent-interface 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.

spf timers delay-interval hold-interval

undo spf timers

View

OSPFv3 view

Default level

2: System level

Parameters

delay-interval: Specifies the interval between when OSPFv3 receives a topology change and when it starts SPF calculation. The value range is 0 to 65535 seconds.

hold-interval: Specifies the hold interval between two consecutive SPF calculations. The value range is 0 to 65535 seconds.

Description

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

Use undo spf timers 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.

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 stub to configure an area as a stub area.

Use undo stub 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.

Default level

2: System level

Parameters

router-id: Specifies the router ID for a virtual link neighbor.

hello seconds: Specifies the interval in seconds for sending Hello packets. The value range is 1 to 8192, and the default is 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. The value range is 1 to 3600, and the default is 5.

trans-delay seconds: Specifies the delay interval in seconds for sending LSA packets. The value range is 1 to 3600, and the default is 1.

dead seconds: Specifies the neighbor dead time in seconds. The value range is 1 to 32768, and the default is 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: Specifies the instance ID of a virtual link, in the range of 0 to 255. The default is 0.

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

Description

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

Use undo vlink-peer 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.
