[BUG] VRRP ipv6 packets from EOS not arriving at hosts in clab case

[jbemmel]

Using the VRRP ipv6 test from #1782:

• netlab up integration/gateway/03-vrrp-ipv6.yml -p libvirt -d eos works
• netlab up integration/gateway/03-vrrp-ipv6.yml -p clab -d eos does not work

For some reason the bridge created by Netlab drops the VRRP packets and IPv6 RA packets, resulting in no ipv6 default routes at the hosts

I have tried various things to make the bridges more similar in settings, but am still having trouble understanding why the bridge forwards in the first case, and drops in the second case. tcpdump on the bridge shows packets arriving

Could be, but in my case also libvirt + frr doesn’t work - only EOS. I’ll try on a different system
