iven the network diagram in the following graphic, write out the
OSPF-specific configuration to create the virtual link that would be required for this topology.
Recall that all areas need a link back to the backbone area. If an area is not physically adjacent to the backbone area, then a virtual link can be used to span the transit area that separates the area from the backbone area. In this exercise, since Area 1 does not attach directly to Area 0, we need to create a virtual link across the transit area (Area 2).
