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 timer.
•
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 timer.
•
Determine the ACL rule for register message filtering.
•
Determine the register suppression time.
•
Determine the register probe time.
•
Determine the ACL rule and sequencing rule for disabling a switchover to SPT.
Enabling PIM-SM
When PIM-SM is 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.
All interfaces on the same router or in the same VPN instance on the same router must be configured
with the same PIM mode.
