Active state In the Active state, the BGP speaker is attempting to initiate a TCP session with the
BGP speaker it wants to peer with. Once the connection is successfully completed, the BGP speaker
clears the ConnectRetry timer, completes initialization, sends an OPEN message to the remote BGP
speaker, and transitions its state to OpenSent. If the ConnectRetry timer expires, the BGP speaker
resets the timer, initiates a TCP session, continues to listen for an attempted connection from the
remote BGP speaker, and transitions to the Connect state. If the BGP speaker detects another BGP
speaker trying to form a TCP session with it and the remote BGP speaker’s IP address is not the
expected IP address, the BGP speaker rejects the connection, resets the ConnectRetry timer, continues
to listen for an attempted connection from the remote BGP speaker, and stays in the Active state.
If any other types of events cause an error, the BGP speaker closes the TCP connection and transitions
its state to Idle. All BGP start events are ignored in the Active state.
