This field Displays
IP Address The IP address of the neighbor.
Routes Received How many routes the device has received from the neighbor during the current BGP4
session:
• Accepted or Installed - Number of received routes the device accepted and installed
in the BGP4 route table.
• Filtered or Kept - Number of routes that were filtered out, but were retained in
memory for use by the soft reconfiguration feature.
• Filtered - Number of received routes filtered out.
Routes Selected as
BEST Routes The number of routes that the device 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 not installed in the IP route table because the device 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
device 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.
NLRIs Received in
Update Message The number of routes received in Network Layer Reachability (NLRI) format in
UPDATE messages:
• Withdraws - Number of withdrawn routes the device has received.
• Replacements - Number of replacement routes the device has received.
NLRIs Discarded
due to Indicates the number of times the device discarded an NLRI for the neighbor due to the
following reasons:
• Maximum Prefix Limit - The configured maximum prefix amount had been reached.
• AS Loop - An AS loop occurred. An AS loop occurs when the BGP4 AS-path
attribute contains the local AS number.
• maxas-limit aspath - The number of route entries discarded because the AS path
exceeded the configured maximum length or exceeded the internal memory limits.
• Invalid Nexthop - The next-hop value was not acceptable.
• Duplicated Originator_ID - The originator ID was the same as the local device ID.
• Cluster_ID - The cluster list contained the local cluster ID, or the local device ID (see
above) if the cluster ID is not configured.
