Hi Internetwork experts!

I have the following scenario in a pim sparse ONLY network:

                              ------------LINK A-----------------
RouterA(R.P) ------------LINK B-----------------
ROUTERB(M.A)
                              ------------LINK B-----------------
I have a PIM sparse only network, enabled with autorp for dynamic rp
mapping, and all three links have full reachability by an igp.

I think I should use multicast static routes but in what direction? from the
R.P. to the M.A.? or frm or from the M.A towards the R.P? or both??
Once defined, what is the best syntax to create the static mroute?
using syntax of the next hop, or of the egress interface in the multicast
static route:

ip mroute 0.0.0.0 0.0.0.0 serial0
ip mroute 0.0.0.0 0.0.0.0 15.15.15.1 (Next hop router)

thanks.
