Field Information displayed
NOTE
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 device 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
messages with the neighbor.
If there is more BGP4 data in the TCP receiver queue, a plus sign (+) is
also displayed.
NOTE
If you display information for the neighbor using the show ip
bgp neighborip-addr command, the TCP receiver queue value
will be greater than 0.
