Implementing Cisco Service Provider Advanced Routing Solutions (SPRI) — Question 68

For which reason can two BGP peers fail to establish a neighbor relationship?

Answer options

• A. Their BGP send-community strings are misconfigured
• B. Their BGP timers are mismatched
• C. Their remote-as numbers are misconfigured
• D. They are both activated under an IPv4 address family

Correct answer: C

Explanation

The correct answer is C, as BGP peers must have matching remote-as numbers to establish a relationship. Options A and B are not critical for the initial establishment of a neighbor relationship, while option D is irrelevant since both peers can be in the same address family and still fail to connect.
