Rendezvous Point Configuration and Static RP Configuration

Rendezvous Point Configuration and Static RP Configuration

There is not a default RP and one or more must be configured using one of the three methods. For the static case, the RP does not need to be configured, only the leaf routers. To configure the static RP, use the global configuration command

ip pim rp-address ip-address [access-list-number] [override]

ip-address

ip address of the RP

group-access-list-number

Optional. Standard IP access list number, 1—100. If no access list is used, then the RP can handle all groups. Use an access list to limit the groups that the RP will service.

override

Optional. If there is a conflict between the static RP and one configured using Auto-RP, then the static RP takes precedence.

For example, to configure an RP that handles all groups, use

ip pim rp-address 172.16.1.1

where 172.16.1.1 is the address of the RP. If we want the RP to only handle a subset of multicast groups, then an access list is needed. If the RP is to handle only group 239.252.1.1, then we would use the following commands:

ip pim rp-address 172.16.1.1 1

access-list 1 permit 239.252.1.1 0.0.0.0

If the RP is to service the groups 239.252.1.0 through 239.252.1.255, then the access list would contain

access-list 1 permit 239.252.1.0 0.0.0.255.
