4. To view a specific router configuration, use the show running-config
command in Privileged EXEC mode.
5. Try to ping another device that is on the same network that has a routing
problem.
6. Make sure that there is a network router configuration command specified for
the network to which the interface belongs. For example, if you assign the new
interface IP address 10.10.10.0, enter the following commands to enable RIP
on the interface:
RDN(config)#router rip
RDN(config-rip)#network 10.10.10.5 255.255.255.0
Ensure that process IDs, addresses, and other variables are properly specified
for the routing protocol you are using.
Routing Interface Down
Use the following steps to activate a routing interface:
1. Use the show ip interfaces brief command in Privileged EXEC mode to see
whether the interface is administratively down, as shown in the following
example:
RDN#show ip interfaces brief
Check the command output to determine if the Ethernet or POS interface is
administratively down.
2. If the interface is administratively down, bring it up using the no shutdown
command in Interface Configuration mode, as shown in the following
example:
RDN(config)#interface {<interface> | <slot>/<interface number>}
where:
interface is either identified as ethernet or POS.
slot number refers to the POS, or SRM module slot number on the BSR
64000.
