How to disable multicast snooping on bridges

Title says it all.

I have a few Incus bridges where I need to disable multicast snooping as they’re causing long delays in NDP between containers.

How can I tell Incus to disable it?

We don’t have a config option for it, but you can likely set it through /sys/class/net/incusbr0/bridge/multicast_snooping or equivalent, unless you’re on something locked down like IncusOS.

Thanks @stgraber ! I was looking at setting it at the OS level, but I’m also planning to move to IncusOS. Is this a planned feature? Should I open a ticket somewhere to request it if not?

Yeah, feel free to file a feature request against Incus. We can probably add an ipv6.multicast_snooping type config for this.
