thanks and yes, working on it....
i've done my best to recreate this scenario in my lab...
21.2R3-S4.8 - in lab - problem not seen
20.2R3-S7.3 - in lab - downgraded an hour ago - problem not seen
19.2R3-S6.1 - in lab - downgrading now... will let you know... if good,
will continue
18.3R3-S6.1 - will move to this if problem not seen in 19.2
17.4R2-S11 - will move to this if problem not seen in 18.3...this 17.4
is what is in the field

Hi Aaron,
as you're using a 3,5 years old junos, is it possible to upgrade and check if
the problem is fixed in a newer version?
The latest is from March 2022, but I would still expect some bug fixing.
Maybe there is something wrong in the programming of the hardware...
Kind regards

does this help?
ACX5048
- port ge-0/0/4 - vlan 100 - multicast listener/client
- port ge-0/0/5 - vlan 100 - multicast listener/client
- port ge-0/0/6 - vlan 100 - multicast listener/client
- irb.100 routes that vlan - runs pim/igmp/igmp-snooping l2-querier
- xe-0/0/0 - an uplink port running pim to route ssm multicast joins to
the multicast sender
- port ge-0/0/2 is mapped to an l2circuit over mpls to some remote location
--- i don't see ge-0/0/2 related at all to the vlan 100 where i run
multicast

Hi Aaron,
It's not clear from your explanation where l2circuits with ospf are
connected and how they are related to this irb/vlan.
Do you really need a querier in this case? IIRC, querier is needed
when only hosts are present on LAN and a switch has to send igmp
queries. In your case, you have a router with irb interface that
should work as igmp querier by default. Not sure if it helps though.
Kind regards,
Andrey

I'm having an issue where igmp snooping layer 2 querier breaks ospf in
other devices which are in l2circuits
Has anyone ever come across this issue, and have a work-around for it?
I have the following configured and devices in vlan 100 can join
multicast just fine. But there are other unrelated l2circuits that
carry traffic for devices in other vlans and inside this l2circuit is
ospf hellos that seem to be getting broken by this configuration
set interfaces irb unit 100 family inet address 10.100.4.1/27
set protocols ospf area 0.0.0.1 interface irb.100 passive
set protocols igmp interface irb.100 version 3
set protocols pim interface irb.100
set protocols igmp-snooping vlan vlan100 l2-querier source-address
10.100.4.1
Model: acx5048
