Yaiy, iEdon's #dn42 map got support for the #BGP #multicast channel!! You can change the channel via the new button in the top right which initially says "ALL".

At IETF 125 there will be a meeting to discuss #multicast for AI networks.

They really do want to ruin *everything*

GOD DAMN IT:

https://www.libertysys.com.au/2022/12/pain-points-mld-snooping-on-linux-bridges/

There's a bug in #multicast snooping that breaks neighbor discovery, and apparently #proxmox enables snooping by default on bridges... This is causing all my headaches! and it's an OLD bug from back in 2013 or more! #librecast @librecast

do you guys know anything about this?

Pain points: MLD snooping on Linux bridges

It seems that MLD snooping on Linux bridges has broken various parts of IPv6 connectivity over the past 10 years or so. Initial reports...

Yes, it disappears and then I can't ND to the router, and ping won't work.

Why does the #linux bridge lose track of the fact the router wants that #multicast group?

This is so cursed #IPv6 #multicast

So having cables plugged in to the router will successfully deliver the packets to the devices. But not on wlan on the same router. Any settings on the router related to multicast such as igmp snooping is set correctly as far as I understand #IPv6 #multicast

This is really fucking annoying tbh #IPv6 #multicast

Besides the crates not supporting receiving multicast messages it seems there might also be an issue where my router isn’t sending the packets on the wireless links #IPv6 #multicast

Narrowing it down to possibly esp-hal not fully supporting setting the options to set the interface to listen to the multicast group. #RustLang #multicast #smoltcp
