A multicast network is using bidirectional PIM. Which two actions, when combined, can achieve high availability so that two RPs within the same network can act in a redundant manner? (Choose two.)
A. Use Anycast RP based on MSDP peering between the two RPs.
B. Use a phantom RP address.
C. Advertise routes for the two RPs with the same subnet mask through the unicast routing protocol.
D. Advertise routes for the two RPs with different subnet mask lengths through the unicast routing protocol.
E. Manipulate the administrative distance of the unicast routes to the two RPs.
F. Manipulate the multicast routing table by creating static mroutes to the two RPs.
