Configuring a Static PIM Rendezvous Point

If a static PIM Rendezvous Point (RP) network IP address is used for a particular
multicast group, this IP address must be configured on all RP routers. First-hop
routers send registration packets to the RP IP address on behalf of source multicast
hosts. Routers also use this IP address on behalf of multicast hosts that want to
become members of a multicast group. These routers send Join and Prune messages to
the RP. The RP must be a PIM router; however, it does not require any special
configuration to recognize that it is the RP. Also, RPs are not members of the
multicast group; rather, they serve as a "meeting place" for multicast sources and
group members.
A single RP can be configured for more than one group. The conditions specified by
the access list determine which PIM multicast groups use the RP. If no access list is
configured, the RP is used for all multicast groups. A statically configured RP takes
precedence over any dynamically learned RP.
Follow these steps to configure a static PIM Rendezvous Point (RP):
1. Use the router pim command in Global Configuration mode to enter Router
2. Use the pim rp-address command in Router Configuration mode to configure
9-4
A.B.C.D is the wild-card mask for the PIM network.
Configuration mode:
MOT(config)# router pim
the static PIM RP IP address for a particular multicast group:
MOT(config-pim)# pim rp-address <A.B.C.D> [<1-99>]
where:
A.B.C.D is the unicast IP address of a PIM RP for a multicast group.
1-99 is the multicast optional group number, which is a standard IP access list
number. If no number is entered, the multicast group defaults to the entire
Class D IP address group range.
The following example sets the PIM RP address to 200.63.25.35 for all multicast
groups:
MOT(config-pim)# pim rp-address 200.63.25.35
The following example sets the PIM RP address to 147.106.6.22 for the multicast
group 225.2.2.2 only:
MOT(config)# access-list 1 permit host 225.2.2.2
