Configuration prerequisites
Before you configure PIM-DM, configure a unicast routing protocol so that all devices in the domain
can interoperate at the network layer
Enabling PIM-DM
Enable IP multicast routing before you configure PIM.
With PIM-DM enabled on interfaces, routers can establish PIM neighbor relationship and process
PIM messages from their PIM neighbors. As a best practice, enable PIM-DM on all non-boarder
interfaces of routers when you deploy a PIM-DM domain.
IMPORTANT:
All the interfaces on a device must operate in the same PIM mode in the public network or the same
VPN instance.
To enable PIM-DM:
Step
Enter system view.
1.
Enable IP multicast routing
2.
and enter MRIB view.
Return to system view.
3.
Enter interface view.
4.
Enable PIM-DM.
5.
Enabling the state refresh feature
In a PIM-DM domain, this feature enables the PIM router that is directly connected to the source to
periodically send state refresh messages. It also enables other PIM routers to refresh pruned state
timers after receiving the state refresh messages. It prevents the pruned interfaces from resuming
multicast forwarding. You must enable this feature on all PIM routers on a subnet.
To enable the state refresh feature:
Enabling PIM-DM
