Example 7-34and Example 7-35show the addition of OSPF to the Core switches. As in Example 7-33 on page 130, it is assumed that RIP is not present or has been removed.

Example 7-34 Configuration for Core switch 1

router ospf 9

network 10.35.0.0 0.0.255.255 area 0.0.0.9 network 10.45.0.0 0.0.255.255 area 0.0.0.9

!turn RIP off no router rip

Example 7-35 Configuration for Core switch 2

router ospf 9

network 10.36.0.0 0.0.255.255 area 0.0.0.9 network 10.46.0.0 0.0.255.255 area 0.0.0.9 !turn rip off

no router rip

Verifying operation of this configuration

The following commands verify that the environment is working as advertised. As with the configuration examples, you can use the ping and tracert/traceroute commands to test end-to-end connectivity.

GbESM commands to verify RIP

The /i/l3/route/dump command (as shown in Example 7-36)shows the entire IP routing table on the GbESM. Routes learned from other routers are shown as indirect rip or indirect ospf. Other routes are shown as direct or local. This is a very useful command in all Layer 3 configurations. The /i/l3/rip/dump and /i/l3/rip/route commands provide more detailed information about the operation of RIP.
