Description: This attribute indicates the current state of this BGP peer connection. The meaning of each state is as follows: idle - it is the initial state of the BGP peer connection. Error events will also cause BGP peer connection to transit to the idle state. connect - BGP has initiated a TCP connection request to this peer, and waiting for reply from that peer. active - BGP is not initiating a TCP connection request to this peer, because TCP connection failed and is waiting for connection retry time-out. openSent - a TCP connection to this peer has been established, but the OPEN message has not been successfully exchanged. openConfirm - OPEN message has been successfully exchanged with this peer, but the first KEEPALIVE message has not been received from that peer. established - the first KEEPALIVE message has been received from this peer, which means this BGP peer connection has been established. See RFC 1771 for a detailed description of BGP state transitions.
What is mscVrIpBgpPeerConnectionState?
Tracks this BGP peer session's progress through the RFC 1771 finite-state machine: idle, connect, active, openSent, openConfirm, and finally established once the first KEEPALIVE is received. An admin reads this to diagnose why a peer session isn't coming up, e.g. stuck at connect means the TCP handshake to the peer isn't completing.
