Configuration Guide 21. IP Multicast – PIM Sparse Mode
21 IP Multicast – PIM Sparse Mode
Protocol-Independent Multicast (PIM) is a family of multicast routing protocols for Internet
Protocol (IP) networks that provide one-to-many and many-to-many distribution of data
over a LAN, WAN or the Internet. It is termed protocol-independent because PIM does not
include its own topology discovery mechanism; however, instead uses routing information
supplied by other routing protocols.
There are four variants of PIM. AudioCodes supports the most common variant:
PIM Sparse Mode (PIM-SM) explicitly builds unidirectional shared trees rooted at a
rendezvous point (RP) per group, and optionally creates shortest-path trees per source.
PIM-SM generally scales fairly well for wide-area usage.
21.1 Feature Key
Advanced routing feature key must be enabled. Some networks require dynamic routing
protocols- OSPF\BGP and VRF capabilities. To support these capabilities, the appropriate
Feature key should be set.
21.2 CLI Configuration and Status Commands
The following describes the CLI Configuration and Status commands.
21.2.1 Configuration Commands
Command Description
MSBR# configure data
Enters the data configuration menu.
ip multicast-routing
Enables the multicast protocol on the
MSBR.
mode pim
exit
Sets multicast mode to PIM and returns
to
configure data.
ip pim rp-address <ip> group <Multicast
group prefix>
Sets static RP address for router, should
be configured on all related PIM routers.
ip pim rp-candidate <IP | Interface>
priority <0-255> time <0-3600>
 Sets router to be a candidate RP,
chosen by priority.
 Sets router to be a candidate RP,
Advertising Interval in seconds.
 When interface is used – the RP
candidate will be set to interface IP.
ip pim bsr-candidate <IP | Interface>
priority <0-255>
 Sets router to be a BSR candidate,
chosen by priority when Interface is
used – the BSR candidate will be set
to interface IP.
