Displaying Route Information for a Neighbor

You can display routes based on the following criteria:

•A summary of the routes for a specific neighbor.

•The routes received from the neighbor that the routing switch selected as the best routes to their destinations.

•The routes received from the neighbor that are the best BGP4 routes to their destinations, but were nonetheless not installed in the IP route table because the routing switch received better routes from other sources (such as OSPF, RIP, or static IP routes).

•The routes that are unreachable because the routing switch does not have a valid RIP, OSPF, or static route to the next hop.

•Routes for a specific network advertised by the routing switch to the neighbor.

•The Routing Information Base (RIB) for a specific network advertised to the neighbor. You can display the RIB regardless of whether the routing switch has already sent it to the neighbor.

To display route information for a neighbor, use the following CLI methods.

USING THE CLI

Displaying Summary Route Information

To display summary route information, enter a command such as the following at any level of the CLI:

HP9300(config-bgp-router)# show ip bgp neighbor 192.168.4.211 routes-summary

Routes Received:18, Accepted/Installed:18, Filtered:0 Routes Selected as BEST Routes:17
