Which multicast rendezvous-point redundancy mode is supported for Bidirectional PIM?

  • A Embedded RP
  • B Phantom RP
  • C MSDP
  • D PIM anycast RP
Explanation

Phantom RP provides redundancy for Bidirectional PIM. It uses a virtual, unassigned RP address and routing-based failover between candidate RPs while preserving the single shared tree rooted at that address. Anycast RP and MSDP are not Bidirectional PIM RP-redundancy mechanisms.
