PR doc error, fix planned(!) for 11.4(!) (read: end of year or so,
perhaps, let's see).
It's indeed PR/456700 - we ran into it with DHCPv6 (goes to
all-dhcp-agents :1:2 address). There seems to be a misprogramming of the
mcast MAC destination filters by IGMP snooping as 33:33:00:00:00:xx
destinations (like e.g. ND etc.) passes fine, but 33:33:00:00:01:xx gets
blocked (like DHCPv6 :1:2 and your :1:5).
I have no luck in convincing JNPR that this issue should be fixed any
quicker.
It's told to affect all EX series, I verified on EX3200, others on
EX8200.
Bottom line: no DHPCv6 in IGMP snooping enabled VLANs on EX \o/.
Best regards,
Daniel
