Hi Nik, hi Ido,

By the way speaking about the IGMP/MLD querier mechanism. Not sure if
you are subscribed to the pim@...f.org or mcast-wifi@...f.org mailing lists.

There was a call for volunteers to progress IGMP/MLD to standards
track not that long ago:

"[pim] Volunteers needed for work on progressing IGMP/MLD on the standards track"
https://mailarchive.ietf.org/arch/msg/pim/F5y_w6jnrtzBpEiC7F_TxBv9PXI

I had voiced some concerns regarding the IGMPv2/MLDv1 report
suppression and the querier mechanism and their unfavourable
implications, as well as some issues (or ambiguities at least) with RFC4541:

https://mailarchive.ietf.org/arch/msg/pim/DWWYpnsZsbqHtafwYZ_swhDpbcQ
https://mailarchive.ietf.org/arch/msg/pim/omI4-pg-12vO88YuZcRP5TCz4wY


It seems that some bigger vendors had gathered for a phone call:

https://mailarchive.ietf.org/arch/msg/pim/jPAbf-PHgtgpwe8lgyjOzCHlhc0

But I haven't heard anything back from that meeting on those
lists.


Just wanted to forward this, in case you guys might maybe be
interested to participate there in some way. :-)

Cheers, Linus
