Question

Refer to the exhibit. A network support engineer for ASN 65502 receives a technical support ticket from a customer in ASN 65503 who reports that an eBGP session is down. The engineer determines that the peering failed after a recent change to the device at 192.168.26.2. EDGE- GW-1 must establish an eBGP session with the peering router 192.168.26.2. Which configuration establishes this session?

Why each option

To establish an eBGP session between EDGE-GW-1 in ASN 65502 and the peering router 192.168.26.2 in ASN 65503, the engineer must configure the BGP router process and define the neighbor with its remote AS.

Aconfigure terminal

This choice is syntactically identical to choice D, which is the correct answer. The exact distinction in the original question cannot be determined from the provided text.

Bconfigure terminal

This choice is syntactically identical to choice D, which is the correct answer. The exact distinction in the original question cannot be determined from the provided text.

Cconfigure terminal

This choice is syntactically identical to choice D, which is the correct answer. The exact distinction in the original question cannot be determined from the provided text.

Dconfigure terminalCorrect

To establish an eBGP session, the engineer needs to enter global configuration mode (`configure terminal`), define the local BGP Autonomous System (`router bgp 65502`), and then specify the remote eBGP neighbor. This involves using the `neighbor 192.168.26.2 remote-as 65503` command, where `192.168.26.2` is the peer's IP address and `65503` is its Autonomous System Number. These commands collectively configure EDGE-GW-1 to initiate and maintain an eBGP peering session with the specified remote router.
