Example

Router 1

Router 1(rw-config)->router ospf 1
Router 1(rw-config-ospf-1)->area 0.0.0.1 virtual-link 2.2.2.2
Router 1(rw-config-ospf-1)->exit
Router 1(rw-config)->

Router 2

Router 2(rw-config)->router ospf 2
Router 2(rw-config-ospf-2)->area 0.0.0.1 virtual-link 1.1.1.1
Router 2(rw-config-ospf-2)->exit
Router 2(rw-config)->

Configuring Area Virtual-Link Timers

The following timers can be configured for an area virtual-link:

• Dead-interval using the area virtual-link dead-interval command
• Hello-interval using the area virtual-link hello-interval command
• Retransmit-interval using the area virtual-link retransmit-interval command
• Transmit-delay using the area virtual-link transmit-delay command

See Configuring OSPFv3 Timers for an OSPF timers discussion.

Note

RFC 2328 specifies that the retransmit-interval should be greater than the expected round-trip delay between the two routers. This may be hard to estimate for a virtual-link; it is better to err on the side of making it too large.
