TABLE 21 BGP4+ neighbor route summary information
This field... Displays...
IP Address The IPv6 address of the neighbor
Routes Received How many routes the Virtual ADX device has received from the neighbor during
the current BGP4+ session:
•
Accepted or Installed – Indicates how many of the received routes the
Virtual ADX 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 Virtual ADX 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 Virtual ADX device received better routes from other
sources (such as OSPFv3 or static IPv6 routes).
Unreachable Routes The number of routes received from the neighbor that are unreachable
because the Virtual ADX device does not have a valid 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Withdraws – The number of withdrawn routes the Virtual ADX device has
received.
•
Replacements – The number of replacement routes the Virtual ADX
device has received.
NLRIs Discarded due to Indicates the number of times the Virtual ADX device discarded an NLRI for the
neighbor due to the following reasons:
•
Maximum Prefix Limit – The Virtual ADX 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.
Routes Advertised The number of routes the Virtual ADX device has advertised to this neighbor:
•
To be Sent – The number of routes the Virtual ADX device has queued to
send to this neighbor.
•
To be Withdrawn – The number of NLRIs for withdrawing routes the Virtual
ADX device has queued up to send to this neighbor in UPDATE messages.
