OSPFv2 Virtual Links

Overview
Each area border router (each router connected to two or more areas) must have access to
the backbone area for reasons associated with the protocol. If such a router is not connected
directly to the backbone area, a virtual link to the backbone area is created.
In this menu, you can monitor this virtual link.
