22 PIM
PIM (Protocol Independent Multicast) is a multicast routing architecture that allows the addition of
IP multicast routing on existing IP networks. Multicast IP Routing protocols are used to distribute
data to multiple recipients. Using multicast, a source can send a single copy of data to a single
multicast address, which is then distributed to an entire group of recipients. A multicast group
identifies a set of recipients that are interested in a particular data stream, and is represented by
an IP address from a well-defined range. Data sent to this IP address is forwarded to all members
of the multicast group.
PIM is unicast routing protocol independent and can be operated in two mode : dense and
sparse. It is designed to provide scalable inter-domain multicast routing across the Internet. PIM
provides multicast routing and forwarding capability to the switch. It maintains the integrity of the
hardware based multicast forwarding table with respect to the forwarding table existing in the
software. It is independent of the underlying unicast routing protocol and uses the information
from the Unicast Routing protocol.

set ip pim threshold
set ip pim spt-switchperiod
set ip pim rp-threshold
set ip pim rp-switchperiod
set ip pim regstop-ratelimit-period
set ip pim pmbr
ip pim component
set ip pim static-rp
set mode
rp-candidate rp-address
rp-candidate holdtime
rp-static rp-address
ip pim query-interval
