BGP peering and route updates

BGP peering and route update messaging is explored in detail in this flow.

This message flow shows how two BGP routers:

  1. Peer by establishing a TCP connection and exchanging BGP OPEN messages.
  2. Exchange Keep Alive messages to ensure that the routers are reachable.
  3. Exchange routes using BGP UPDATE messages.
  4. Release the BGP connection on operator command.
All messages in this sequence diagram may be clicked to see complete field level details of every BGP message.
