State
The state of this switch 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 switchhas queued to send to this neighbor.
