Displaying BGP4+ information
Syntax: show ipv6 bgp neighbor [ipv6-address] routes-summary
This display shows the following information.
TABLE 120 BGP4+ neighbor route summary information
This field... Displays...
IP Address The IPv6 address of the neighbor
Routes Received How many routes the device has received from the neighbor during the current
BGP4+ session:
•
Accepted or Installed – Indicates how many of the received routes the
device accepted and installed in the BGP4+ route table.
•
Filtered or Kept – Indicates how many routes were filtered out, but were
nonetheless retained in memory for use by the soft reconfiguration
feature.
•
Filtered – Indicates how many of the received routes were 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 IPv6
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 IPv6
route table because the device received better routes from other sources (such
as OSPFv3, RIPng, or static IPv6 routes).
Unreachable Routes The number of routes received from the neighbor that are unreachable
because the device does not have a valid RIPng, OSPFv3, or static IPv6 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Withdraws – The number of withdrawn routes the device has received.
•
Replacements – The 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 device’s 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 Address – 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 device has advertised to this neighbor:
•
To be Sent – The number of routes the device has queued to send to this
neighbor.
•
To be Withdrawn – The number of NLRIs for withdrawing routes the device
has queued up to send to this neighbor in UPDATE messages.
