● group-address group-address mask—Enter the keyword group-address, then the group-
address mask in dotted-decimal format (/xx) to assign the group address to the RP.
● [override]—Overrides BSR updates with static RP for groups with the same prefix length.
Default None
Command Mode CONFIGURATION
Usage
Information
First hop routers use this address to send register packets on behalf of the source multicast hosts. The
RP addresses are stored in the order in which they are entered. The RP is chosen based on a longer prefix
match for a group. You can specify the range of group addresses for which a given node is configured as
an RP. The RP selection does not depend on static or dynamic RP assignments.
If you have configured a static RP for a group, use the override option to override BSR updates with
static RP configuration.
If you do not explicitly use the override option and:
● The prefix length of the static RP is the same as the BSR RP, the BSR RP takes precedence over
statically configured RP.
● If the prefix length of the static RP and the BSR RP does not match, OS10 selects the router having
the longest-match prefix as the RP.
The no form of this command removes static RP configuration.
Example
OS10# configure terminal
OS10(config)# ip pim rp-address 171.1.1.1 group-address 225.1.1.3/32

ip pim rp-candidate
Configures the router as an IPv4 PIM RP candidate.
Syntax
ip pim [vrf vrf-name] rp-candidate {ethernet node/slot/port[:subport] |
loopback loopback-interface-number | vlan vlan-number | port-channel port-
channel-number} [priority priority-value] [acl acl-name]
Parameters
● vrf vrf-name—Enter the keyword vrf, then the name of the VRF
● loopback-interface-number—Enter a value from 0 to 16383
● vlan-number—Enter a value from 1 to 4093
● port-channel-number—Enter a value from 1 to 128
● priority-value—Enter a value from 0 to 255
● acl-name—Standard ACL name
Default Priority is 192.
Command Mode CONFIGURATION
Usage
Information
Specify the interface to obtain the candidate RP address. The access-list acl-name adds a range of
group addresses that this candidate RP can serve.
If you do not specify an access list, the C-RP advertises itself to the entire multicast range, 224.0.0.0./4.
If you specify an access list, the C-RP advertises only the group range that the access list permits.
The no form of the command removes the router from being a C-RP. You must specify the parameters
with the no form of this command.
Example
OS10# configure terminal
OS10(config)# ip pim vrf red rp-candidate loopback 10 priority 11 acl rp-
