Displaying BGP4+ information
45
State The state of this switch’s neighbor session with each neighbor. The
states are from this switch’s perspective of the session, not the
neighbor’s perspective. The state values can be one of the following for
each switch:
•
IDLE – The BGP4+ process is waiting to be started. Usually,
enabling BGP4+ or establishing a neighbor session starts the
BGP4+ process.
•
A minus sign (-) indicates that the session has gone down
and the software is clearing or removing routes.
•
ADMND – The neighbor has been administratively shut down.
•
A minus sign (-) indicates that the session has gone down
and the software is clearing or removing routes.
•
CONNECT – BGP4+ is waiting for the connection process for the
TCP neighbor session to be completed.
NOTE: ACTIVE – BGP4+ is waiting for a TCP connection from the
neighbor.
If the state frequently changes between CONNECT and ACTIVE,
there may be a problem with the TCP connection.
•
OPEN SENT – BGP4+ is waiting for an Open message from the
neighbor.
•
OPEN CONFIRM – BGP4+ has received an OPEN message from the
neighbor and is now waiting for either a KEEPALIVE or
NOTIFICATION message. If the switch receives a KEEPALIVE
message from the neighbor, the state changes to Established. If the
message is a NOTIFICATION, the state changes to Idle.
•
ESTABLISHED – BGP4+ is ready to exchange UPDATE packets with
the neighbor.
•
If there is more BGP data in the TCP receiver queue, a
plus sign (+) is also displayed.
NOTE: If you display information for the neighbor using the show ipv6
bgp neighbor <ipv6-address> command, the TCP receiver queue
value will be greater than 0.
Time The time that has passed since the state last changed.
Accepted The number of routes received from the neighbor that this switch
installed in the BGP4+ route table. Usually, this number is lower than the
RoutesRcvd number. The difference indicates that this switch filtered
out some of the routes received in the UPDATE messages.
Filtered The routes or prefixes that have been filtered out.
•
If soft reconfiguration is enabled, this field shows how many routes
were filtered out (not placed in the BGP4+ route table) but retained
in memory.
•
If soft reconfiguration is not enabled, this field shows the number
of BGP4+ routes that have been filtered out.
Sent The number of BGP4+ routes that the switch has sent to the neighbor.
ToSend The number of routes the switch has queued to send to this neighbor.
