Configuration prerequisites
Before you configure PIM-SM, configure a unicast routing protocol so that all devices in the domain
can interoperate at the network layer.
Enabling PIM-SM
Enable IP multicast routing before you configure PIM.
With PIM-SM enabled on interfaces, routers can establish PIM neighbor relationship and process
PIM messages from their PIM neighbors. As a best practice, enable PIM-SM on all non-border
interfaces of routers when you deploy a PIM-SM domain.
IMPORTANT:
All the interfaces on the same router must operate in the same PIM mode in the public network or
the same VPN instance.
To enable PIM-SM:
Step
1.
Enter system view.
