Changing the dead interval on a virtual link

For more information, see Adjusting virtual link performance by changing the interface settings.


area area-id virtual link ip-address dead-interval 1-65535

Used in the router OSPF context on both ABRs in a virtual link to change the number of seconds that a neighbor router waits for a hello packet from the specified interface before declaring the interface "down." This should be some multiple of the hello interval. The dead-interval setting must be the same on both ABRs on a given virtual link.


Specifies the OSPF area in which both ABRs in a given virtual link operate. In this use, the area ID is sometimes termed "transit area ID."

This value must be the same for both ABRs in the virtual link.


For an ABR in a given virtual link, this is the IP address used to create the link on that ABR.

This IP address matches the IP address of the interface on the opposite end of the virtual link. See the description of ip-address in the syntax description under Configuring a virtual link.

Use show ip ospf virtual-link ip-address to view the current setting.

Default: 40 seconds; range: 1–65535 seconds
