Layer 3 Routing Commands 1379
If the router receives an UPDATE message with an invalid path attribute, the
router will in most cases send a NOTIFICATION message and reset the
adjacency. BGP maintains a per-neighbor counter for each type of path
attribute error. This show command lists each non-zero counter, just after the
LastSubError. The counters that may be listed are as follows:
Warning Only on Prefix
Limit
Whether to shutdown a neighbor that exceeds the
prefix limit. TRUE if the event is logged without
shutting down the neighbor.
Minimum Advertisement
Interval
The minimum time between UPDATE messages sent to
this neighbor.
MD5 Password The TCP MD5 password, if one is configured, in plain
text.
Last Error The last error that occurred on the connection to this
neighbor.
Last SubError The suberror reported with the last error.
Established Transitions The number of times the adjacency has transitioned
into the Established state.
Established Time How long since the connection last transitioned to or
from the Established state.
Time Elapsed Since Last
Update
How long since an UPDATE message has been received
from this neighbor.
Message Table The number of BGP messages sent to and received from
this neighbor
Prefixes Advertised A running count of the number of prefixes advertised to
or received from this neighbor
Prefixes Withdrawn A running count of the number of prefixes included in
the Withdrawn Routes portion of UPDATE messages,
to and from this neighbor
Prefixes Current The number of prefixes currently advertised to or
received from this neighbor
Max NLRI per Update The maximum number of prefixes included in a single
UPDATE message, to and from this neighbor
Min NLRI per Update The minimum number of prefixes included in a single
UPDATE message, to and from this neighbor
