Example 7-34 and Example 7-35 show 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.
Example 7-36 GbESM commands to verify RIP
