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.
This example creates a virtual link using MD5 authentication.
