This section presents a case study that
addresses the issues associated with integrating RIP with OSPF.
Because complex internetworks typically include UNIX hosts and
legacy routers (neither of which is likely to support OSPF), 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:
- Configuring a RIP network
- Adding OSPF to the core of a RIP
network
- 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 (130.10.0.0) and an 8-bit subnet mask. Each site has a
contiguous set of network numbers, as shown in Figure .
All three routers are connected to
the same major network, so they will each be configured with the network
130.10.0.0 command. (Click on
the topology in Figure
to view the running configs of each router).
