Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
Before configuring PIM-SM, prepare the following data:
z
The IP address of a static RP and an ACL rule defining the range of multicast groups to be served
by the static RP
z
C-RP priority and an ACL rule defining the range of multicast groups to be served by each C-RP
z
A legal C-RP address range and an ACL rule defining the range of multicast groups to be served
z
C-RP-Adv interval
z
C-RP timeout
z
C-BSR priority
z
Hash mask length
z
An ACL rule defining a legal BSR address range
z
BS period
z
BS timeout
z
An ACL rule for register message filtering
z
Register suppression time
z
Register probe time
z
The ACL rule and sequencing rule for SPT switchover
Enabling PIM-SM
With PIM-SM enabled, a router sends hello messages periodically to discover PIM neighbors and
processes messages from the PIM neighbors. When deploying a PIM-SM domain, you are
recommended to enable PIM-SM on all non-border interfaces of the routers.
Enabling PIM-SM globally
Follow these steps to enable PIM-SM:
