Router(config-router)#

 

 

 

 

Step 5

end

Exits router configuration mode, and enters

 

Example:

privileged EXEC mode.

 

 

 

Router(config-router)# end

 

 

Router#

 

 

 

 

Example

The following configuration example shows RIP version 2 enabled in IP network 10.0.0.0 and 192.168.1.0.

To see this configuration, use the show running-configcommand from privileged EXEC mode.

!

Router# show running-config

router rip version 2 network 10.0.0.0 network 192.168.1.0 no auto-summary

!

Verifying Configuration

To verify that you have properly configured RIP, enter the show ip route command and look for RIP routes signified by “R.” You should see a verification output like the example shown below.

Router# show ip route
