Indicating the hello interval on a virtual link


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

Used in the router OSPF context on both ABRs in a virtual link to indicate the length of time between the transmission of hello packets between the ABRs on opposite ends of the virtual link.

The hello-interval setting must be the same on both ABRs on a given virtual link.

Default: 10 seconds; range: 1–65535 seconds


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.
