Chapter 7. Nortel Networks L2/3 GbESM configuration and network integration

/cfg/l3/rip/off
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
/i/l3/route/dump
