Delaying sending the BGP open message
Syntax:
Parameters bgp open-on-accept
Delays sending the BGP Open message until an OPEN message is received. When this command is specified, an OPEN message will be immediately sent when the TCP connection has completed for configured peers. If the peer is not configured (is matched by an allow clause, but not a peer command), it will continue to wait for the OPEN message from the remote peer before sending its own BGP OPEN message.
