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

The received-routes option lists all the route information received in route updates from the

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.
