Web - Click Routing Protocol, OSPF, Virtual Link Configuration. To create a new

virtual link, specify the Area ID and Neighbor Router ID, configure th e link attributes,

and click Add. To modify the settings for an existing link, click the Detail button for

the required entry, modify the link settings, and click Set.

Figure3-136 OSPF Virtual Link Configuration

CLI - This example configures a virtual link from the ABR adjacent to area 0.0.0.4,

through a transit area to the neighbor router 10.1.1.252 at the other end of the link

which is adjacent to the backbone.
