Which two statements correctly describe the RPF check when a multicast packet arrives at a router? (Choose two.)
Which two statements correctly describe the RPF check when a multicast packet arrives at a router? (Choose two.)A . The router looks up the source address in the unicast routing table to determine if the packet has arrived on the interface that is on the reverse path back to the...
