Use this command to configure the dead interval for an OSPF sham link.
| area-id | Specifies the OSPF area the two PE routers belong to. |
| source-ip-address | Specifies the source IP address for this sham link. |
| destination-ip-address | Specifies the destination IP 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. |
The dead interval defaults to 60 seconds.
VRF configuration, OSPF router configuration.
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.
This example shows how to configure a sham link dead interval to 80 seconds between two PE routers with a source address of 172.16.1.10 and a destination address of 172.16.2.20 on OSPF router instance 10, VRF doc:
System(su)->router doc System(su-doc)->configure System(su-doc-config)->router ospf 10 System(su-doc-config-ospf-10)->enable-pe-ce System(su-doc-config-ospf-10)->area 10 sham-link 172.16.1.10 172.16.2.20 dead-interval 80
