This lab features the same topology as Lab 9-4 (Figure 9-3) with the difference that all UNIX gateways are running the Zebra zebra/ospfd now instead of GateD. However, they are implementing the same functionality.
NOTE
The configurations of the Cisco IOS routers are exactly as in Lab 9-4; therefore, they are omitted here.
Examples 9-19 to 9-21 present the Zebra ospfd configurations and relevant show commands for the three UNIX gateways callisto, castor, and ganymed. These examples also show the routing situation from the gateway's routing table point of view. Therefore, we can compare the OSPF RIB link-state database (LSDB) and the UNIX forwarding table.
Example 9-19. Zebra OSPF Configuration and Output on Callisto
