Configuration prerequisites
Before you configure PIM-SM, complete the following tasks:
• Configure any unicast routing protocol so that all devices in the domain are interoperable at the
network layer.
• Determine the IP address of a static RP and the ACL rule defining the range of multicast groups to
be served by the static RP.
• Determine the C-RP priority and the ACL rule defining the range of multicast groups to be served by
each C-RP.
• Determine the legal C-RP address range and the ACL rule defining the range of multicast groups to
be served.
• Determine the C-RP-Adv interval.
• Determine the C-RP timeout.
• Determine the C-BSR priority.
• Determine the hash mask length.
• Determine the ACL rule defining a legal BSR address range.
• Determine the BS period.
• Determine the BS timeout.
• Determine the ACL rule for register message filtering.
• Determine the register suppression time.
• Determine the register probe time.
• Determine the multicast traffic rate threshold, ACL rule, and sequencing rule for an SPT switchover.
• Determine the interval of checking the traffic rate threshold before an 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. To deploy a PIM-SM domain, enable PIM-SM on all
non-border interfaces of the routers.
To enable PIM-SM on the public network:
