Bug Description
During manual testing L3 HA on scale(env-11 3 controllers, 46 computes VxLAN) was found instability in rescheduling routers behavior. As a result connection was established after longer period of time than it is expected.
During multiple reboots of (primary and non-primary) controllers (multiple restart of L3 agents) with large amount of routers >=175 after recover of rebooted node(start L3 agent that was banned) multiple agents try to become active(master):
http://
http://
After around 5 minutes only one agent is "active" and connection established normal.
This issues is floating: was reproduced with 175 routers and then with 200 routers was not reproduced(during rebooting of controllers), then it was reproduced with 200 routers and was not reproduced for 250 routers (ban/clear l3 agent).
