[Note]
If both the RP that was learned by the BSR and the static RP exist simultaneously, the RP that was learned by the BSR is given
priority for use. If there are multiple RPs that were learned by the BSR, the RP is selected using the RP priority and hash
function.
If multiple static RPs exist, the RP with the largest IP address is selected as the RP.
If the group range specified by the IPv4 access list does not exist, or if "any" is specified, the group range will be 224.0.0.0/4
(all multicast group addresses).
When a group range is specified in the IPv4 access list, this should be set to "permit" for the multicast group that is managed by
the RP.
[Example]
Specify VLAN #2 as a candidate RP for all multicast group addresses 224.0.0.0/4.
SWX3220(config)#ip pim rp-candidate vlan2
8.4.9 Set Candidate-RP-Advertisement message
[Syntax]
ip pim crp-fixed-prefix
no ip pim crp-fixed-prefix
[Initial value]
none
[Input mode]
global configuration mode
[Description]
If nothing is specified for the multicast group range on the rendezvous point (C-RP), this sets Prefix Count = 1, and configures
the Candidate-RP-Advertisement to be transmitted for Group = 224.0.0.0/4 (all multicast groups).
If this command is executed with the "no" syntax, returns to the operations set by default.
If nothing is specified for the multicast group range using the ip pim rp-candidate command by default, this sets Prefix Count
= 0, and transmits the Candidate-RP-Advertisement message without Group information.
[Example]
If nothing is specified for the multicast group range in the C-RP settings, this sets Prefix Count = 1, and transmits the
Candidate-RP-Advertisement message for Group = 224.0.0.0/4.
SWX3220(config)#ip pim crp-fixed-prefix
