352-001 Question #784: Real Exam Question with Answer & Explanation

The correct answer is A: embedded RP. IPv6 PIM-SM supports Embedded RP and BSR as standards-based dynamic RP discovery mechanisms, while Auto-RP and MSDP are IPv4-only and MLD is unrelated to RP discovery.

Question

Which two design option are available to dynamically discover the RP in an IPv6 multicast network? (Choose two)

Options

Aembedded RP
BMSDP
CBSR
DAuto-RP
EMLD

Explanation

IPv6 PIM-SM supports Embedded RP and BSR as standards-based dynamic RP discovery mechanisms, while Auto-RP and MSDP are IPv4-only and MLD is unrelated to RP discovery.

Common mistakes.

B. MSDP is an IPv4-only inter-domain protocol used to advertise active multicast sources between PIM-SM domains, not a mechanism for discovering the RP within a domain.
D. Auto-RP is a Cisco-proprietary RP discovery mechanism that relies on IPv4 multicast groups (224.0.1.39 and 224.0.1.40) and is not supported in IPv6 multicast networks.
E. MLD is the IPv6 equivalent of IGMP and handles host-to-router group membership reporting; it has no role in RP discovery within a PIM multicast domain.
