Dear all,

For the problem of unnecessary multicast flooding in the source network, which is 
described in the problem-statement draft and presented by DengHui at IETF79 meeting, 
we have uploaded two solution drafts, one for the FHR(First hop router) and the other
for the switches in the source netwrok.

http://datatracker.ietf.org/doc/draft-dizhou-pim-umf-problem-statement/ 

http://datatracker.ietf.org/doc/draft-zhou-pim-fhr-source-network-prohibition/

http://datatracker.ietf.org/doc/draft-zhou-pim-source-network-pim-snooping/

Besides the problem, there is no protocol for switches in the source network at present. 
We hope there would be a protocol to prohibit multicast stream at the exact switch.

The solution above is suitable for PIM SSM/SM/DM. 

Besides the solution based on pim-snooping and pim, the solution based on igmp extension
works too, which was described in the problem-statement draft.  

We welcome your comments and discussions on it,

Thanks and Regards,

ZhouDi
