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.
USING THE CLI
