        The other non-DR devices will not send register messages to the
RP, hence the (S,G) tree cannot be built from the source to the RP.
Create an SVI on one of the switches that's not routing multicast on the
segment that you want the server to be on and generate traffic from
there. This would be a more accurate test because the routers would
then just be forwarding the multicast traffic, not generating it
locally.

Hi Group,

I am working with multicast in my lab. I configure PIM sparse-dense
and if I makes ping from router (DR) to a group does not work, but
change the ip pim dr-priority and router from which I make ping is not
DR works fine.
Ping never works if router from which I do ping is DR.

Please, let me know your opinion.
Thanks a lot.
AA
