When a routing entry is deleted from the multicast routing table, the corresponding forwarding entry will
also be deleted from the multicast forwarding table.

Network requirements

PIM-DM runs in the network. All routers in the network support multicast. SecPath A, SecPath B and

SecPath C run OSPF.
Typically, Receiver can receive the multicast data from Source through the path SecPath A – SecPath B,

which is the same as the unicast route.
Perform the following configuration so that Receiver can receive the multicast data from Source through

the path SecPath A – SecPath C – SecPath B, which is different from the unicast route.
