Hi Pani,

           Yes it is mandatory to create and keep the (S,G) state on FHR so
that periodic NULL register packets keep the the (S,G) state on the RP
alive. Otherwise, how else do you restart the traffic when the receivers
join? Are you using BSR based source signaling or something similar?

            If the group falls in SSM range then no need to create (S,G)
state from data.

Thanks,
Indranil
