[Openstack-operators] Router associated with multiple l3 agents

The HA routers feature we merged in Juno, and those are scheduled to
multiple agents.
If you source admin credentials and 'neutron router-show
951c8ec9-9a6c-4c6d-9d6d-049b3dee7f6f'
is the 'HA' flag set to True? Otherwise, this is a really weird bug
which I've never seen before.
