The <ip-addr> option lets you narrow the scope of the command to a specific neighbor.
The advertised-routes option displays only the routes that the Layer 3 Switch has advertised to the neighbor
during the current BGP4 neighbor session.
The attribute-entries option shows the attribute-entries associated with routes received from the neighbor.
The flap-statistics option shows the route flap statistics for routes received from or sent to the neighbor.
The last-packet-with-error option displays the last packet from the neighbor that contained an error. The
packet's contents are displayed in decoded (human-readable) format.
The received prefix-filter option shows the Outbound Route Filters (ORFs) received from the neighbor. This
option applies to cooperative route filtering.
The received-routes option lists all the route information received in route updates from the neighbor since the
soft reconfiguration feature was enabled. See “Using Soft Reconfiguration” on page 21-100.
The routes option lists the routes received in UPDATE messages from the neighbor. You can specify the following
additional options:
• 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.
