Lab 26 – OSPF Virtual Link Example 3

Prerequisites: CCNP level skills.
Note!
Virtual links are also used to connect dis-contiguous area 0 (e.g. company aquisition etc.)

Topology

Pic. 1 – OSPF Topology.
Task 1
Configure OSPF so that area 0 is contiguous as per OSPF design requirements. Do not change areas already configured.

Lab Solution

Note!
Before configuring a virtual link, the routing tables are incomplete due to the fact that the backbone area (area 0) is dis-contiguous.
