Displaying BGP4 information

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 Layer 3 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 Layer 3 switch received better
routes from other sources (such as OSPF, RIP, or static IP routes).

The routes that are unreachable because the Layer 3 switch does not have a valid RIP, OSPF, or
static route to the next hop.

Routes for a specific network advertised by the Layer 3 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 Layer 3 switch has already sent it to the neighbor.

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