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 routing
entry will also be deleted from the multicast routing table.
Configuration Examples
Changing an RPF Route
Network requirements
• PIM-DM runs in the network. All devices in the network support multicast.
• Device A, Device B and Device C run OSPF.
• Typically, Receiver can receive the multicast data from Source through the path Device A – Device
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 Device A – Device C – Device B, which is different from the unicast route.
