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-border
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
1. Enter system view.
2. Enable IP multicast routing
and enter MRIB view.
3. Return to system view.
4. Enter interface view.
5. Enable PIM-DM.
Enabling the state refresh feature
In a PIM-DM domain, the state refresh 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:
