In order to be able to use multicast on your network you need to configure one or more rendezvous point routers (RP routers). An RP router accepts registrations both from multicast receivers and senders. An RP router is a regular PIM-SM router that is chosen to be the RP router for certain multicast groups as well. All PIM-SM routers must agree on which router is to be the RP router.
To create an RP router, do the following:
On the RP Routers tab, click New Rendezvous Point Router.
The dialog box Add RP Router opens.
Specify the following settings:
Name: Enter a descriptive name for the RP router.
Host: Create (or select) the host that should act as rendezvous point router.
Priority: Enter a number that defines the priority of the RP router. Join messages are sent to the RP router with the lowest priority. Numbers from 0 to 255 are possible. If you do not provide a priority, 0 is used by default.
Multicast Group Prefixes: Enter the multicast group the RP router is responsible for. You can define group prefixes like 184.108.40.206/24 if the RP is responsible for more than one multicast group. The multicast group (prefix) must be within the multicast address range which is 220.127.116.11/4.
Comment (optional): Add a description or other information.
The new RP router is added to the routers list.
To either edit or delete an RP router, click the corresponding buttons.
