William: The configuration is OK as described. Not enough information for
a complete answer but some suggestions are:
1. Check the IP routing table on State for the route to the HQ e0 subnet.
And on HQ for the State s1 network. Both of these must be present for the
ping to work.
If not there, correct IGP.
2. Check the mroute table on HQ for the (S,224.10.10.1) where S is the s1
interface on State, the originator of the pings. If this entry is there
then the pings were received on HQ (using a continuous ping from State to
224.10.10.1). If not present then there is a more basic connectivity
problem.
If still having problems send output from sh ip route, sh ip mroute, and sh
ip pim nei on all three routers.
HTH, Fred
