Configuration examples

Changing an RPF route

Network requirements
PIM-DM runs in the network. All switches in the network support multicast. Switch A, Switch B and Switch
C run OSPF. Typically, the receiver host can receive the multicast data from the source through the path:
Switch A to Switch B, which is the same as the unicast route.
Perform the configuration so that the receiver host receives the multicast data from the source through the
path: Switch A to Switch C to Switch B, which is different from the unicast route.
Command
display multicast routing-table static [ source-address { mask-length | mask } ]
display multicast rpf-info source-address [ group-address ]
reset multicast forwarding-table { { source-address [ mask { mask-length |
mask } ] | group-address [ mask { mask-length | mask } ] | incoming-interface
{ interface-type interface-number } } * | all }
reset multicast routing-table { { source-address [ mask { mask-length | mask } ] |
group-address [ mask { mask-length | mask } ] | incoming-interface
interface-type interface-number } * | all }
