non-backbone areas should keep connectivity with the backbone area and the
backbone area must keep connectivity in itself.
If the physical connectivity cannot be ensured due to various restrictions, you can
configure OSPF virtual links to satisfy this requirement.
4.4.1 Configuration Prerequisites
Before configuring OSPF area attributes, perform the following tasks:
z
Configuring the network layer addresses of interfaces so that the adjacent nodes
are reachable to each other at the network layer
