C H A P T E R 1 1 RIP and OSPF
Area 5 is connected to the backbone area by way of ABR1 and
ABR2. It is located in Chicago and has the following
characteristics:
• Network number 160.26.x.x
• 1 identified VLAN (Chi_160_26_26)
• 2 internal routers
• A virtual link from ABR1 to ABR2 that traverses both internal
routers.
In the event that the link between either ABR and the backbone
fails, the virtual link provides a connection for all routers that
become discontiguous from the backbone.
Area 6 is a stub area connected to the backbone by way of ABR1. It
is located in Los Angeles and has the following characteristics:
• Network number 161.48.x.x
• 1 identified VLAN (LA_161_48_2)
• 3 internal routers
• Uses default routes for inter-area routing
Two router configurations for the example in Figure 25 are
provided in the following section.
