Scenario 4-4: OSPF and Integrated IS-IS Redistribution
In this scenario, you integrate the IS-IS network you configured in Scenario 4-3 with an OSPF network. Figure 4-7 displays the OSPF network and IS-IS. Router R1 has loopbacks ranging from 131.108.2.0 to 131.108.15.255.
Figure 4-7. OSPF and Integrated IS-IS Network Topology
Because R4 is within both the OSPF and IS-IS domain, you can configure redistribution between OSPF and IS-IS.
To configure redistribution between any IP routing protocols, you must configure a metric that is used within the IP dynamic routing protocol. For OSPF, you must define a cost metric, for example.
