Based on the show ip bgp summary output, which two statements are true? (Choose two.)
A.
The BGP session to the 10.1.1.1 neighbor is established.
B.
The BGP session to the 10.2.2.2 neighbor is established.
C.
The BGP session to the 10.3.3.3 neighbor is established.
D.
The router is attempting to establish a BGP peeringsession with the 10.1.1.1 neighbor.
E.
The BGP session to the 10.3.3.3 neighbor is established, but the router has not received
any BGP routing updates from the 10.3.3.3 neighbor.
F.
The router is attempting to establish a BGP peeringsession with the 10.2.2.2 neighbor.
Explanation:
The main point of this question is the “State/PfxRcd” column, which shows the BGP states.
Below is the list of BGP states in order, from startup to peering:
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 establishmentof a TCP connection or the reestablishment 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 OpenSentstage; if the connection cannot
complete, BGP goes to Active
3 – Active:In the Active state, the BGP speaker is attemptingto initiate a TCP session with
the BGP speaker it wants to peer with. If this can be done, the BGP state goes to OpenSent
state.
4 – OpenSent:the BGP speaker is waiting to receive an OPEN message from the remote
BGP speaker
5 – OpenConfirm:Once the BGP speaker receives the OPEN message andno error is
detected, the BGP speaker sends a KEEPALIVE messageto the remote BGP speaker
6 – Established:All of the neighbor negotiations are complete. Youwill see a number (2 in
this case), which tells us the number of prefixes the router has received from a neighbor or
peer group.
