You are designing an IPv4 any source multicast redundancy solution. Which technology ensures the quickest RP convergence?

Auto-RP relies on Candidate-RP announcements and a Mapping Agent to distribute RP information, introducing timer-based delays before a new RP is recognized network-wide.

Embedded RP is an IPv6-only mechanism that encodes the RP address within the multicast group address itself and is not applicable to IPv4 ASM deployments.

Bootstrap Router (BSR) requires BSR election and propagation of the RP-set via bootstrap messages throughout the PIM domain, which introduces significant convergence delay compared to anycast RP.

With MSDP Anycast RP, multiple physical RPs are configured with the same loopback (anycast) IP address and exchange source information via MSDP. When one RP fails, PIM neighbors automatically begin using another RP at the same anycast address through normal unicast routing convergence, eliminating the need for a new RP election and providing near-instantaneous failover.
