snBgp4NeighborSummaryState

1.3.6.1.4.1.1991.1.2.11.17.1.1.3

Syntax: Integer

Read-only

Shows the state of the BGP4 process during the current session with the neighbor:

  • noState(0)
  • idle(1) - 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.
  • connect(2) - Waiting for the connection process for the TCP neighbor session to be completed.
  • active(3) - BGP4 is waiting for a TCP connection from the neighbor.
  • openSent(4) - BGP4 is waiting for an OPEN message from the neighbor.
  • openConfirm(5) - BGP4 has received an OPEN message from the neighbor and is now waiting for either a KEEPALIVE or NOTIFICATION message. If the router receives a KEEPALIVE message from the neighbor, the state changes to established(6). If the message is a NOTIFICATION, the state changes to idle(1).
  • established(6) - BGP4 is ready to exchange UPDATE messages with the neighbor.
Note: If there is more BGP data in the TCP receiver queue, a plus sign (+) is also displayed.
