Given the following scenario:
A large corporate network is configured for IP multicast routing using PIM Sparse mode only.
In an effort to limit multicast traffic on the network, each router has only a static RP mapping for the group range 239.0.0.0 0.0.0.255. No other RPs exist on this network.
If a client or source attempts to perform an IGMP join for a group outside of the 239.0.0.0 range, will the registration fail at the first hop, or will the group fall back to dense mode?
