Viewing Routes Learned from a Specific Protocol

Problem

You have configured a routing protocol and you want to make sure the router is learning routes from that protocol.

Solution

Include the protocol name in the show route command:

	aviva@RouterG>  
show route protocol isis
	inet.0: 18 destinations, 18 routes (18 active, 0 holddown, 0 hidden)
	+ = Active Route, - = Last Active, * = Both
	10.0.2.0/24 *[IS-IS/18] 00:45:17, metric 20
	 > to 10.0.1.1 via fe-0/0/1.0
	 to 10.0.0.2 via fe-1/0/1.0
	10.0.8.0/24 *[IS-IS/18] 00:45:17, metric 20
	 > to 10.0.0.2 via fe-1/0/1.0
	10.0.21.0/24 *[IS-IS/15] 00:45:17, metric 20
	 > to 10.0.16.1 via fe-1/0/0.0
	10.0.24.0/24 *[IS-IS/18] 00:45:17, metric 20
	 > to 10.0.1.1 via fe-0/0/1.0
	10.0.29.0/24 *[IS-IS/18] 00:45:17, metric 30
	 > to 10.0.1.1 via fe-0/0/1.0
	192.168.14.1/32 *[IS-IS/18] 00:45:17, metric 20
	 > to 10.0.1.1 via fe-0/0/1.0
	192.168.17.1/32 *[IS-IS/18] 00:45:17, metric 10
	 > to 10.0.0.2 via fe-1/0/1.0
	192.168.18.1/32 *[IS-IS/18] 00:45:17, metric 10
	 > to 10.0.1.1 via fe-0/0/1.0
	192.168.42.1/32 *[IS-IS/15] 00:45:17, metric 10
	 > to 10.0.16.1 via fe-1/0/0.0

 

Discussion

When you are setting up routing protocols on your network, use the show route protocol command to make sure that each router has a route to each other router and that the routes are being directed out the proper interface on the router. In this recipe, we are setting up an IS-IS network and checking that the local IS-IS router has learned routes to all IS-IS destinations.
