Configuration prerequisites

Before you configure PIM-DM, configure any unicast routing protocol so that all devices in the domain
are interoperable 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. When you deploy a PIM-DM domain, enable PIM-DM on all
non-border interfaces of the routers.
IMPORTANT:
All the interfaces on a device must operate in the same PIM mode.
To enable PIM-DM:
Step
1. Enter system view.
2. Enable IP multicast routing.
3. Enter interface view.
4. Enable PIM-DM.

Enabling the state refresh feature

Pruned interfaces resume multicast forwarding when the pruned state times out. To prevent this, the router
with the multicast source attached periodically sends an (S, G) state refresh message, which is forwarded
