Alcatel-Lucent NRS II – Multicast Routing — Question 12

Why do RPs configured for anycast RP-set exchange Register messages?

Answer options

• A. To inform each RP about all of the multicast sources in the domain
• B. There is no need for this. This is purely an optional functionality as described in the anycast RP draft
• C. To inform each RP about all of the multicast enabled receivers
• D. To facilitate the anycast RP election process
• E. None of the above

Correct answer: B

Explanation

The correct answer is B, as Register messages are not required and are considered optional according to the anycast RP draft. Option A is incorrect because the messages do not inform RPs about multicast sources, while option C is also incorrect as they do not share information about multicast receivers. Option D is wrong because the Register messages do not facilitate the election process for anycast RPs.
