View

OSPFv3 area view

Default Level

2: System level

Parameters

ipv6-address: Destination IPv6 address prefix of the summary route.

prefix-length: Length of the prefix.

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 configured 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

seconds: Dead time in seconds.

instance-id: Instance ID of an interface, 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 not supported on P2MP and NBMA interfaces at present.

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.

Default Level

2: System level

Parameters

seconds: Interval between hello packets in seconds.

instance-id: Instance ID of an interface, which defaults to 0.

Description

Use the ospfv3 timer hello command to configure the hello interval for an interface that belongs to an instance.

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

By default, the hello interval is 10 seconds for P2P and Broadcast interfaces, and is not supported on the P2MP or NBMA interfaces at present.

Related commands: ospfv3 timer dead.

Examples

# Configure the hello interval as 20 seconds for VLAN-interface 10 in instance 1.

1.1.37  ospfv3 timer retransmit

Syntax

ospfv3 timer retransmit interval [ instance instance-id ]

undo ospfv3 timer retransmit [ instance instance-id ]

View

Interface view

Default Level

2: System level

Parameters

interval: LSA retransmission interval in seconds.

instance-id: Instance ID of an interface, 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 device 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

1.1.38  ospfv3 trans-delay

Syntax

ospfv3 trans-delay seconds [ instance instance-id ]

undo ospfv3 trans-delay [ instance instance-id ]

View

Interface view

Default Level

2: System level

Parameters

seconds: Transmission delay in seconds.

instance-id: Instance ID of the interface. The default is 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

[Sysname] interface vlan-interface 10

[Sysname-Vlan-interface10] ospfv3 trans-delay 3 instance 1

1.1.39  preference

Syntax

preference [ ase ] [ route-policy route-policy-name ] preference

undo preference [ ase ]

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 the preference for specific routes.

Preference: Preference for OSPFv3 routes.

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 device 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

[Sysname] OSPFv3

[Sysname-OSPFv3-1] preference 150

Parameters

router-id: 32-bit router ID, in dotted decimal 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 device running an OSPFv3 process in the autonomous system. The OSPFv3 process cannot run without a Router ID.

Make sure that different processes have different Router IDs.

Related commands: ospfv3.

 

 

Examples

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

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 sending OSPFv3 packets.

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

An interface is able to send OSPFv3 packets by default.

Multiple processes can disable the same interface from 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 sending OSPFv3 packets in OSPFv3 processes 100 and 200.

<Sysname> system-view

[Sysname] ospfv3 100

1.1.42  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.

hold-interval: Hold interval in seconds between two consecutive SPF calculations.

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 device 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.

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

1.1.43  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 it configured, the ABR advertises only a default route in a Summary-LSA to the stub area (such an area is called 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 devices 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

[Sysname-ospfv3-1] area 1

1.1.44  vlink-peer (OSPFv3 area view)

Syntax

vlink-peer router-id [ hello seconds | retransmit seconds | trans-delay seconds | dead seconds | instance instance-id ] *

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

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. 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 default is 5.

trans-delay seconds: Specifies the delay interval in seconds for sending LSA packets. The default is 1.

dead seconds: Specifies the neighbor dead time in seconds. 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: Instance ID of an virtual link. The default is 0.

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 direct connection with the backbone area or for a backbone area that cannot maintain connectivity, you can use the vlink-peer command to create logical connectivity. A virtual link can be considered as an interface with OSPFv3 enabled, because parameters such as hello, retransmit and trans-delay are configured in the similar way.

Examples

# Create a virtual link to 10.110.0.3.

<Sysname> system-view

[Sysname] ospfv3 1

[Sysname-ospfv3-1] area 10.0.0.0
