Question:
A local router shows an EBGP neighbor in the Active state. Which statement is true about the local router?

  • A. The local router is attempting to open a TCP session with the neighboring router.
  • B. The local router is receiving prefixes from the neighboring router and adding them in RIB-IN.
  • C. The local router has active prefixes in the forwarding table from the neighboring router.
  • D. The local router has BGP passive mode configured for the neighboring router.

Explanation: The BGP session may report in the following states
1 – Idle: the initial state of a BGP connection. In this state, the BGP speaker is waiting for a BGP start event, generally either the establishment of a TCP connection or the re-establishment of a previous connection. Once the connection is established, BGP moves to the next state.
2 – Connect: In this state, BGP is waiting for the TCP connection to be formed. If the TCP connection completes, BGP will move to the Open Sent stage; if the connection cannot complete, BGP goes to Active
3 – Active: In the Active state, the BGP speaker is attempting to initiate a TCP session with the BGP speaker it wants to peer with. If this can be done, the BGP state goes to Open Sent state.
4 – Open Sent: the BGP speaker is waiting to receive an OPEN message from the remote BGP speaker
5 – Open Confirm: Once the BGP speaker receives the OPEN message and no error is detected, the BGP speaker sends a KEEPALIVE message to the remote BGP speaker
6 – Established: All of the neighbor negotiations are complete. You will see a number, which tells us the number of prefixes the router has received from a neighbor or peer group.
