Currently, number of no-working routers keeps increasing.

Hi Team,
As the customer has closed the case now and we are unable to reproduce, I will be closing this bugzilla now.
If you suspect you are hitting this same issue please check router status on all 3 controllers with something like [1]
If you see the route status for a given router is master on all 3 controllers, you can test recreating it and checking the status once more.
Some things that may be relevant:
- neutron l3-agent-list-hosting-router <UUID> output were void for the failing routers
- Environment was recently updated from 13.0.16 to 16.2.4
- Issue didn't reoccur after routers were recreated.
If your issue matches some of the above, please reopen this bugzilla.
Thanks!
