Hello.,
I deploy a multi node cluster with 2 network nodes
separately with l3_ha=true and max_l3_agents_per_router=2. It is ok but
when I restart neutron_l3_agent on a host which has an active router then 2
routers  become standby-standby or active-active.
I feel 2 network nodes very easily to split brain. Could I have some ideas
on this problem. Thank you.
