serviced by the RP.
Console(config)#ip pim rp-address 192.168.1.1
Console(config)#ip pim rp-address 192.168.2.1 group-prefix 224.9.0.0
255.255.0.0

no ip pim rp-candidate interface vlan vlan-id
vlan-id - VLAN ID (Range: 1-4094)
group-address - An IP multicast group address. If a group address
is not specified, the RP is advertised for all multicast groups.
mask - Subnet mask that is used for the group address.
seconds - The interval at which this device advertises itself as an RP
candidate. (Range: 60-16383 seconds)
value - Priority used by the candidate RP in the election process.
The RP candidate with the largest priority is preferred. If the priority
values are the same, the candidate with the larger IP address is
elected to be the RP. Setting the priority to zero means that this
router is not eligible to server as the RP. (Range: 0-255)
