Nice. Juniper went a step farther - IGMP snooping breaks some IPv6
multicast on EX series (e.g. DHCPv6). :-)

Chasing JNPR since November... Not a priority for them to fix though,
I think it's "planned" for end of this year in 11.4 or so. Who needs
DHCPv6 while using IGMP snooping anyway, eh? :-)

So if IGMP snooping already breaks IPv6, I'm really looking forward to
upcoming MLD snooping bugs :-)

Best regards,

PS: PR/456700 - "closed" state and "resolved in" information is bogus,
they don't care to fix that either. It's definately NOT resolved in
10.4R3. And it affects more than just EX8200 - personally confirmed
EX3200 and rumor is "all EX".
