The router should be configured with minimum configuration for either the Protocol Independent Multicast (PIM) dense mode or the PIM sparse mode, to ensure that multicast traffic is switched through the router.
Perform these configurations to enable multicast routing on a router:
Enable PIM sparse or dense mode, by issuing the ip pimsparse-dense-mode command on all the multicast interfaces.
In the case of sparse mode, a Rendezvous Point (RP) is to be configured. These are options to configure the RP in PIM sparse mode multicast networks:
Configure a static RP address by issuing the ip pim rp-address<x.x.x.x> command. This method is not scalable, and is recommended only in very small, simple networks.
Auto-RP utilizes the sparse-dense mode, which allows a group to be treated in sparse mode if an RP is known. If an RP is not known, then the group defaults to dense mode. RP information is conveyed to the routers by the Auto-RP mechanism, which uses two well known groups: 184.108.40.206 and 220.127.116.11. The advantage of this is that any change to the RP designation needs to be configured only on the RP routers, and not on the leaf routers, as in the static configuration.

I have a hub router and two spoke routers, and I am having an issue with the VPN working between one spoke and the hub. The hub (a 3925 router) and spoke CME (a 3925 router) works PERFECTLY! But the hub to the other spoke WebTest does not work...
