Hi Slawek,
Did you had a chance to make it work ?
The fact that you see it on both tap interfaces confirms the iptables rules bypass,
now maybe the VMs filter out VLAN 0 depending on the interface type used, or ipv6 is disabled on the iface and you were using 'tcpdump -p', ie non promiscuous mode, thus the RA multicast traffic was not shown.
In my simple test (not OpenStack, just qemu/kvm) I'm using fedora 32 host, ubuntu 20.04 guest and virtio nics.
