HP MSR2003 Configuration Manual page 59

Configure the routers so that the receiver host can receive the multicast data from Source through the path:
Router A to Router C to Router B. This path is different from the unicast route.

Configuration procedure
1. Assign an IP address and subnet mask for each interface according to
shown.)
2. Enable OSPF on the routers in the PIM-DM domain to make sure the following conditions are met:
(Details not shown.)
The routers are interoperable at the network layer.
The routers can dynamically update their routing information.
3. Enable IP multicast routing, and enable IGMP and PIM-DM:
# On Router B, enable IP multicast routing.
<RouterB> system-view
[RouterB] multicast routing
[RouterB-mrib] quit
# Enable IGMP on GigabitEthernet 2/1/1 (the interface that connects to the receiver host).
[RouterB] interface gigabitethernet 2/1/1
[RouterB-GigabitEthernet2/1/1] igmp enable
[RouterB-GigabitEthernet2/1/1] quit
# Enable PIM-DM on the other interfaces.
[RouterB] interface gigabitethernet 2/1/2
[RouterB-GigabitEthernet2/1/2] pim dm
[RouterB-GigabitEthernet2/1/2] quit
[RouterB] interface gigabitethernet 2/1/3
[RouterB-GigabitEthernet2/1/3] pim dm
[RouterB-GigabitEthernet2/1/3] quit
# On Router A, enable IP multicast routing, and enable PIM-DM on each interface.
