Designing Cisco Enterprise Networks (ENSLD) — Question 121

A network engineer must design an MSDP multicast solution to provide RP resilience in a network with two separate domains. Also, multicast sources and receivers must register with the local RP. Which solution must the engineer choose?

Answer options

• A. Configure the RP has value to 0, and traffic will route to the closest RP
• B. Configure the RP loopback interface with the same IP address/32, and traffic will route to the closest RP
• C. Configure the RP group ranges to split the multicast traffic, and traffic will route to the longest match
• D. Configure the RP priority with the same value, and traffic will route to the closest RP

Correct answer: B

Explanation

The correct answer is B because configuring the RP loopback interface with the same IP address/32 allows for efficient routing to the nearest RP for both sources and receivers. Options A and D do not effectively ensure RP resilience, while option C focuses on traffic splitting rather than resilience.
