Public bug reported:

Based off Juno GA release bits, testing with L3 agent failover feature by adding following line to neutron.conf file:
allow_automatic_l3agent_failover = True

If we create a couple routers and networks with it, and shutdown network
node with router namespace on it, the router namespace will failover to
other network node (total 3 in my case) after 10 minutes.

If we create 10+ routers and networks associated with each other,
failover does not happen at all if we shutdown any network node. No
routers get migrated to other network node; no errors in neutron logs.

We have tested this on 3 different systems not with DVR configured.

BTW, is there a way to configure how long for failover to happen?
sometimes 10 minutes is a little too long.
