Bug Description
When backup L3 agent in HA deployment is restarted, there is 20-30 seconds of data plane connectivity break to FloatingIP.
It looks that during start of L3 agent, it first enable IPv6 forwarding: https:/
That cause send of MLDv2 packet:
08:38:29.815180 Out fa:16:3e:9e:de:0e ethertype IPv6 (0x86dd), length 112: :: > ff02::16: HBH ICMP6, multicast listener report v2, 2 group record(s), length 48
and that breaks somehow connectivity as packets are sent to backup node instead of master one.
