CCIE Data Center (legacy) — Question 39

Which way to configure a redundant rendezvous point for BIDIR multicast are valid?

Answer options

• A. phantom RP
• B. anycast RP
• C. auto RP
• D. MSDP

Correct answer: B

Explanation

The correct answer is B, anycast RP, which allows multiple RPs to share the same IP address, providing redundancy. Options A (phantom RP) and C (auto RP) do not provide redundancy in the same way, and D (MSDP) is used for interconnecting RPs, but does not inherently provide a redundant RP mechanism.
