Configuring OSPF route redistribution
Configuring basic OSPF in a single area
Configuring basic OSPF across multiple areas
Configuring OSPF route redistribution
Introduction
The following example describes the basic procedure to configure OSPF route redistribution.
Network configuration
As shown in Figure 1, Switch A, Switch B, Switch C, and Switch D run OSPF. Switch C and Switch E are configured with static routes. The AS is split into three areas. Configure the network to meet the following requirements:
· Switch A and Switch B act as ABRs.
· Switch C acts as an ASBR to redistribute external routes (static routes) and correctly advertise routes within the AS.

Configuring basic OSPF across multiple areas
Introduction
The following example describes the procedure to configure basic OSPF across multiple areas.
Network configuration
As shown in Figure 3, Switch A, Switch B, Switch C, and Switch D run OSPF. The AS is split into three areas. Switch A and Switch B act as ABRs. Configure the network to ensure that each switch can learn all of the routes in the AS.
