Comment 16 for bug 1884341

Hi Etienne,

I did tests which You asked for. Here are the results. I used Your scapy script to send packet from my vm1 to vm2.
On tapXXX which belongs to the vm1 I see:

22:49:29.779441 fa:16:3e:fe:ff:f2 > 33:33:00:00:00:01, ethertype 802.1Q (0x8100), length 118: vlan 0, p 0, ethertype 802.1Q, vlan 0, p 0, ethertype IPv6, fe80::f816:3eff:fefe:fff2 > ff02::1: ICMP6, router advertisement, length 56

But I don't see it on any other interface, nor VM2.

sysctl settings which You are asking for:

sudo cat /sys/devices/virtual/net/*/bridge/vlan_filtering
