[j-nsp] EX series and ipv6 multicast / mld.. Doesn't forward with IGMP-SNOOPING enabled

[Chris Evans]

Opened a JTAC case to get some more attention on this.. They're telling me

Rather frustrating, seems like I'm always grinning teeth at JUNOS.. When you
need features, Juniper is lacking.. 18 to 24months behind everyone else.
