NSE7 Advanced Networking and SD-WAN Practice Question

A network administrator is troubleshooting a BGP session between a FortiGate and an ISP router. The administrator runs 'get router info bgp summary' and sees that the BGP state is 'Active'. What does this state indicate?

⚠ Common exam trap

Many exam-takers confuse 'Active' with a session that is actively exchanging routes, but 'Active' specifically refers to the TCP connection phase, not the routing update phase, which only occurs after the session reaches the 'Established' state.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The BGP speaker is trying to establish a TCP connection with the peer

The 'Active' state in BGP indicates that the router is actively trying to initiate a TCP connection to the configured peer. This means the BGP process has moved past the 'Connect' state (where it passively waits) and is now actively sending TCP SYN packets to the peer's port 179, but the three-way handshake has not yet completed. This state is normal during initial session establishment but becomes problematic if it persists, as it typically points to a Layer 3 reachability issue or a firewall blocking TCP/179.
