Command Usage

•All areas must be connected to a backbone area (0.0.0.0) to maintain routing connectivity throughout the autonomous system. If it not possible to physically connect an area to the backbone, you can use a virtual link. A virtual link can provide a logical path to the backbone for an isolated area. You can specify up to 32 virtual links on this router.

•Any area disconnected from the backbone must include the transit area ID and the router ID for a virtual link neighbor that is adjacent to the backbone.

•This router supports up 64 virtual links.

Example

This example creates a virtual link using the defaults for all optional parameters.

Console(config-router)#network 10.4.0.0 0.255.255.0.0 area 10.4.0.0 Console(config-router)#area 10.4.0.0 virtual-link 10.4.3.254 Console(config-router)#

This example creates a virtual link using MD5 authentication.

Console(config-router)#network 10.4.0.0 0.255.255.0.0 area 10.4.0.0 Console(config-router)#area 10.4.0.0 virtual-link 10.4.3.254 message-digest-key 5 md5 ld83jdpq
