P2MP

I got a question from a europe friend, the question is about multicast in junos "P2MP". The main topology is 4 PE adn running L3 vpn in it. and customer running multicast, so the SP needs to carrier the 2xx.x.x.x data to the remote PE, and forward to the CE. the question is, "whean 2 PE are announcing the same's source groups, if i stop one PE, all rsvp tunnel still up when i stop one source. if disconnect one mulitcast source in Lan client...all tunnels fail's"

It's diferent in IOS & Junos for MDT. The first version of the MDT is PE LSR will encap one ipv4 header with multicast address. the multicast address in ipv4 header is MDT group for the VRF. It's unlike the ipv4 unicast label switch. Years later, Juniper launch the P2MP, RSVP-TE function in Junos. And Cisco also announce the mLDP.
