QuestionQ20

IP Multicast

You need to implement fault-tolerant RPs in a multicast network.

Which two solutions provide this behavior?

Choose two
  • A Use BFD with statically defined RPs.
  • B Use MSDP with statically defined RPs.
  • C Use anycast PIM with statically defined RPs.
  • D Use IGMPv3 with statically defined RPs.
Explanation

MSDP enables multiple statically defined RPs to exchange Source-Active information, providing RP redundancy. PIM Anycast RP assigns the same RP address to multiple RPs; after an RP failure, unicast routing converges to another RP and multicast connectivity can be maintained. Cisco documents Anycast RP as providing redundancy and load sharing, with MSDP sharing active-source information between the RPs.
