Enabling PIM-SSM Mapping

The Catalyst 4500 series switch supports SSM mapping, enabling an SSM transition in cases either
where neither URD nor IGMP v3-lite is available, or when supporting SSM on the end system is
impossible or unwanted due to administrative or technical reasons. With SSM mapping, you can leverage
SSM for video delivery to legacy set-top boxes (STBs) that do not support IGMPv3 or for applications
that do not take advantage of the IGMPv3 host stack.

Configuring a Rendezvous Point
A rendezvous point (RP) is required in networks running Protocol Independent Multicast sparse mode
(PIM-SM). In PIM-SM, traffic is forwarded only to network segments with active receivers that have
explicitly requested multicast data.
The most commonly used methods to configure a rendezvous point (described here) are the use of Static
RP and the use of the Auto-RP protocol. Another method (not described here) is the use of the Bootstrap
Router (BSR) protocol.

Purpose
Configures the address of a PIM RP for a particular
group, and specifies bidirectional mode.
Use this command when you are not distributing
group-to-RP mappings using either Auto-RP or the
PIMv2 BSR mechanism
Configures the router to advertise itself as a PIM
Version 2 candidate RP to the BSR, and specifies
bidirectional mode.
Use this command when you are using the PIMv2 BSR
mechanism to distribute group-to-RP mappings.
Configures the router to use Auto-RP to configure the
groups the router is willing to act as RP, and specifies
bidirectional mode.
Use this command when you are using Auto-RP to
distribute group-to-RP mappings.
