Foundry Switch and Router Installation and Configuration Guide
19 - 96 December 2000
• best – Displays the routes received from the neighbor that the Layer 3 Switch selected as the best routes to
their destinations.
• not-installed-best – Displays 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).
• unreachable – Displays the routes that are unreachable because the Layer 3 Switch does not have a valid
RIP, OSPF, or static route to the next hop.
• detail – Displays detailed information for the specified routes. You can refine your information request by
also specifying one of the options above (best, not-installed-best, or unreachable).
The rib-out-routes option lists the route information base (RIB) for outbound routes. You can display all the
routes or specify a network address.
The routes-summary option displays a summary of the following information:
• Number of routes received from the neighbor
• Number of routes accepted by this Layer 3 Switch from the neighbor
• Number of routes this Layer 3 Switch filtered out of the UPDATES received from the neighbor and did not
accept
• Number of routes advertised to the neighbor
• Number of attribute entries associated with routes received from or advertised to the neighbor.
This display shows the following information.
