No connectivity via IPV6 VLAN

[Louis2]

In the past I defined a bridge for a certain VM, however since there is no need for a bridge I decided to remove the bridge and attach the VM directly to the vlan.

That does (as expected) work for IPV4, however I lost IPV6-communication to the VM. I spend some hours searching "every where" what caused this. At the end I decided to create a bridge again. That solved the problem! However, it is NOT ok and it did cost me a couple of hours.

Just for info below a ping test. The upper test was done when the VM was still connected to the VLAN, the second test after modifying the network back to bridge.

I do not know if there is already a ticket for this, if not someone should create one
