OSPF Configuration Example
Configuration for
ABR1

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

The following is the configuration for the router labeled ABR1:
create vlan HQ_10_0_2
create vlan HQ_10_0_3
create vlan LA_161_48_2
create vlan Chi_160_26_2
config vlan HQ_10_0_2 ipaddress 10.0.2.1
255.255.255.0
config vlan HQ_10_0_3 ipaddress 10.0.3.1
255.255.255.0
config vlan LA_161_48_2 ipaddress 161.48.2.2
255.255.255.0
config vlan Chi_160_26_2 ipaddress 160.26.2.1
255.255.255.0
