Table 10.5: BGP4 Route Summary Information for a Neighbor
This Field... Displays...
Routes Received How many routes the routing switch has received from the neighbor
during the current BGP4 session.
• Accepted/Installed – Indicates how many of the received routes
the routing switch accepted and installed in the BGP4 route table.
• Filtered – Indicates how many of the received routes the routing
switch did not accept or install because they were denied by
filters on the routing switch.
Routes Selected as BEST Routes The number of routes that the routing switch selected as the best
routes to their destinations.
BEST Routes not Installed in IP
Forwarding Table
The number of 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 routing switch received better routes
from other sources (such as OSPF, RIP, or static IP routes).
Unreachable Routes The number of routes received from the neighbor that are
unreachable because the routing switch does not have a valid RIP,
OSPF, or static route to the next hop.
History Routes The number of routes that are down but are being retained for route
flap dampening purposes.
