CAUTION:
■ The reset command clears the information in the multicast routing table or the
multicast forwarding table, and thus may cause failure of multicast
transmission.
■ When a routing entry is deleted from the multicast routing table, the
corresponding forwarding entry will also be deleted from the multicast
forwarding table.
■ When a forwarding entry is deleted from the multicast forwarding table, the
corresponding route entry will also be deleted from the multicast routing table.

Network requirements
■ All switches in the network support IP multicast.
■ Switch A, Switch B and Switch C run OSPF, and have no unicast routes to
Switch D.
■ Receiver can receive the multicast data from Source 1 through the path Switch
A - Switch B - Switch C.
■ Perform the following configuration so that Receiver can receive multicast data
from Source 2, which is out of the OSPF domain, through Switch C.
