5
Cisco IOS Release 12.4(15)T
Examples
The sample output displayed for the show ip route command confirms that the administrative distance 
for the IP route 192.168.0.0 255.255.255.0 is 110.
Router# show ip route 192.168.0.0 255.255.255.0
Routing entry for 192.168.0.0/24
Known via "ospf 1", distance 110, metric 0, type intra area
Routing Descriptor Blocks:
* directly connected, via Null0
       Route metric is 0, traffic share count is 1
Troubleshooting Tips
You can research the output from the debug ip ospf rib command to learn about the function of the local 
RIB and the interaction between the route redistribution process and the global RIB. For example, you 
can learn why the routes that OSPF placed in the global RIB are not the same ones that you anticipated.
Configuration Examples for the OSPFv2 Local RIB Feature
Changing the Default Local RIB Criteria: Example

that the local RIB will be used as criteria for all of the following options: forwarding address, inter-area 
summary, and NSSA translation.
