This section presents a case study that addresses the issues associated with integrating RIP with OSPF. Complex internetworks typically include UNIX hosts and legacy routers, neither of which is likely to support OSPF. Because of this, most OSPF internetworks must also use RIP in select areas. This case study provides examples of how to complete the following phases in redistributing information between RIP and OSPF networks:

1. Configuring a RIP network
2. Adding OSPF to the core of a RIP network
3. Adding OSPF areas

Phase 1: Configuring RIP
Figure illustrates the RIP network. Three sites are connected with serial lines.

This RIP network uses a Class B address, 172.16.0.0, and a 24-bit subnet mask.

All three routers are connected to the same major network, so they will each be configured with the

network 172.16.0.0 command. Click on the topology in Figure to view the running configurations of each router.
