Specifying the Rendezvous Point
Using PIM-SM, at least one PIM-capable router must be a candidate for use as a Rendezvous Point 
(RP) for any given multicast group. If desired, the G8124 can act as an RP candidate. To assign a 
configured switch IP interface as a candidate, use the following procedure.
1.
Select the PIM component that will represent the RP candidate:
2.
Configure the IPv4 address of the switch interface which will be advertised as a candidate RP for 
the specified multicast group:
The switch interface will participate in the election of the RP that occurs on the Bootstrap Router, or 
BSR (see 
Alternately, if no election is desired, the switch can provide a static RP, specified using the 
following command:
3.
If using dynamic RP candidates, configure the amount of time that the elected interface will remain 
the RP for the group before a re-election is performed:
RS G8124(config)# ip pim component
<1-2>
RS G8124(config-ip-pim-comp)# rp-candidate rp-address
<group address>
<group address mask> <candidate IPv4 address>
RS G8124(config-ip-pim-comp)# rp-static rp-address
<group address>
<group address mask> <candidate IPv4 address>
RS G8124(config-ip-pim-comp)# rp-candidate holdtime
<1-255>
RS G8124(config-ip-pim-comp)# exit
