OSPF Configuration Example
OSPF Configuration Example is an example of an autonomous system using OSPF routers. The details of this network follow.
OSPF Configuration Example
Area 0 is the backbone area. It is located at the headquarters and has the following characteristics:
- Two internal routers (IR1 and IR2)
- Two area border routers (ABR 1 and ABR 2)
- Network number 10.0.x.x
- Two identified VLANs (HQ_10_0_2 and HQ_10_0_3)
Area 5 is connected to the backbone area by way of ABR 1 and ABR 2. It is located in Chicago and has the following characteristics:
- Network number 160.26.x.x
- One identified VLAN (Chi_160_26_26)
- Two internal routers
Area 6 is a stub area connected to the backbone by way of ABR 1. It is located in Los Angeles and has the following characteristics:
- Network number 161.48.x.x
- One identified VLAN (LA_161_48_2)
- Three internal routers
- Uses default routes for inter-area routing
Configuration for ABR 1 and Configuration for IR 1 provide two router configurations for the example in OSPF Configuration Example.
