Drag and Drop Question
Drag and drop the BGP states from the left to the matching definitions on the right.
Select and Place:
The order of the BGP states is: Idle -> Connect -> (Active) -> OpenSent -> OpenConfirm -> Established
- Idle: No peering; router is looking for neighbor. Idle (admin) means that the neighbor relationship has been administratively shut down.
- Connect: TCP handshake completed.
- Active: BGP tries another TCP handshake to establish a connection with the remote BGP neighbor. If it is successful, it will move to the OpenSent state. If the ConnectRetry timer expires then it will move back to the Connect state. Note: Active is not a good state.
- OpenSent: An open message was sent to try to establish the peering.
- OpenConfirm: Router has received a reply to the open message.
- Established: Routers have a BGP peering session. This is the desired state.
