area sham-link dead-interval

Use this command to configure the dead interval for an OSPF sham link.

Syntax

area area-id sham-link source-ipv6-address destination-ipv6-address dead-interval seconds
no area area-id sham-link source-ipv6-address destination-ipv6-address dead-interval

Parameters

area-id Specifies the OSPF area the two PE routers belong to.
source-ipv6-address Specifies the source IPv6 address for this sham link.
destination-ipv6-address Specifies the destination IPv6 address for this sham link.
seconds (Optional) Specifies the number of seconds that the hello packets of a router are not communicated to neighbor routers before the neighbor routers determine that the router sending the hello packet is out of service. This value must be the same for all nodes attached to a certain subnet, and it is a value ranging from 1 to 2147843647. The default value is 60 seconds.

Defaults

The dead interval defaults to 60 seconds.

Mode

VRF configuration, OSPF router configuration.

Usage

Dead interval must be the same on neighboring routers (on a specific subnet), but can vary between subnets.

The “no” form of this command resets the sham link dead interval to 10 seconds.

Example

This example shows how to configure a sham link dead interval to 80 seconds between two PE routers with a source address of 2001:FA04:0005:0001::0 and a destination address of 2002:FA04:0005:0002::0 on OSPF router instance 10, VRF doc:
