Configuration Examples; Changing An Rpf Route - HP 6125XLG Ip Multicast Configuration Manual

Task
Display information about the
multicast routing table.
Display information about the
static multicast routing table.
Display RPF route information
about the multicast source.
Clear statistics for multicast
forwarding events.
Clear forwarding entries from
the multicast forwarding table.
Clear routing entries from the
multicast routing table.
NOTE:
When a routing entry is removed, the associated forwarding entry is also removed. When a forwarding
entry is removed, the associated routing entry is also removed.

Changing an RPF route

Network requirements
As shown in
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.
Configure the switches so that the receiver host receives the multicast data from the source through the
path: Switch A to Switch C to Switch B. This path is different from the unicast route.
