Active IGMP Snooping and IPv6 LinkLocal fail

Hi,

we use a CRS328-24P-4S+ with the actual firmware 7.18.2 (but the problem is in lower versions the same).

When we activate IGMP Snooping on the bridge we can`t ping IPv6 LinkLocal addresses over this device. Is their additional options, that must be changed? Or is it a bug?

Good Morning

has anyone an idea?

Or it is better to write a direct support request to mikrotik?

Thanks for the answers.
