Displaying BGP4 information
Table 67 lists the field definitions for the command output.
TABLE 67 BGP4 route summary information for a neighbor
Field Description
Routes Received How many routes the Layer 3 switch has received from the neighbor during
the current BGP4 session:
•
Accepted/Installed – Indicates how many of the received routes the
Layer 3 switch accepted and installed in the BGP4 route table.
•
Filtered – Indicates how many of the received routes the Layer 3 switch
did not accept or install because they were denied by filters on the Layer
3 switch.
Routes Selected as BEST Routes The number of routes that the Layer 3 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 Layer 3 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 Layer 3 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.
NLRIs Received in Update
Message The number of routes received in Network Layer Reachability (NLRI) format in
UPDATE messages:
•
Withdraws – The number of withdrawn routes the Layer 3 switch has
received.
•
Replacements – The number of replacement routes the Layer 3 switch
has received.
NLRIs Discarded due to Indicates the number of times the Layer 3 switch discarded an NLRI for the
neighbor due to the following reasons:
•
Maximum Prefix Limit – The Layer 3 switch 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.
•
Invalid Nexthop – The next hop value was not acceptable.
•
Duplicated Originator_ID – The originator ID was the same as the local
router ID.
•
Cluster_ID – The cluster list contained the local cluster ID, or contained
the local router ID (see above) if the cluster ID is not configured.
Routes Advertised The number of routes the Layer 3 switch has advertised to this neighbor:
•
To be Sent – The number of routes the Layer 3 switch has queued to
send to this neighbor.
•
To be Withdrawn – The number of NLRIs for withdrawing routes the Layer
3 switch has queued up to send to this neighbor in UPDATE messages.
