Hi,all
        I am trying to configure multicast spase-mode in Hub-spoke Frame-relay
environment,and got this problem:
        I have tried to make a spoke as the RP,
but when i ping the igmp group which is joined on the Hub's ethernet
interface,I got
two replies from it,not as I expected.When i clear the mroute table,the
first ping
will just got one reply,but the continued pings got two replies.It is
observed that
when i ping from a spoke, there are two packets are send to the ethernet on
the Hub router,and i use all ios 11.2.15(enterprise)on bot routers.
There must be some doohickeys in it, who can tell me why?

Any other suggestions is grateful.

Thanks.
Best Regards

Jansen
