Configuring the OSPF Virtual Links
OSPF requires all areas to be linked through a backbone area. However, if an area is not connected
to a backbone, you can connect two area border routers through a virtual link. Virtual links are
defined by configuring a virtual neighbor. Virtual links cannot be configured through a stub area.
Define virtual links on the
Virtual Links page. To display the Virtual Links page, click Router →
OSPF
→ Virtual Links in the tree view.
