Virtual links are configured for connecting backbone area routers that have no direct physical links.
Virtual links cannot transit a stub area, totally stub area, NSSA area, or totally NSSA area.
To configure a virtual link:
Step
1. Enter system view.
2. Enter OSPF view.
3. Enter area view.
4. Configure a virtual link.

Configuring OSPF network types

OSPF classifies networks into the following types based on the link layer protocol:
Command
system-view
ospf [ process-id | router-id
router-id | vpn-instance
vpn-instance-name ] *
area area-id
nssa [ default-route-advertise |
no-import-route | no-summary |
translate-always |
translator-stability-interval value ]
*
default-cost cost

By default, no virtual link is
configured.
Configure this command on both
ends of a virtual link, and the hello
and dead intervals must be identical
on both ends of the virtual link.
The authentication mode (MD5 or

determined by the authentication
mode configured for the backbone
area.
