Comment 1 for bug 1489183

what's your enviroment ? while in my enviroment,folowing your steps,it's ok!

when the vm is booted,the router is scheduled on the compute node:
[root@controller-kilo ~]# neutron l3-agent-list-hosting-router demo-router
+--------------------------------------+------------------------+----------------+-------+----------+
| id | host | admin_state_up | alive | ha_state |
+--------------------------------------+------------------------+----------------+-------+----------+
| 0ad9782a-2d73-4cf0-9f5a-8762fe312516 | compute-kilo-1 | True | :-) | |
| af482f32-9fd5-43e0-9403-fc49099c5434 | network-kilo.novalocal | True | :-) | |
+--------------------------------------+------------------------+----------------+-------+----------+

when the vm is deleted,the router is not scheduled on the compute node:

[root@controller-kilo ~]# neutron l3-agent-list-hosting-router demo-router
+--------------------------------------+------------------------+----------------+-------+----------+
| id | host | admin_state_up | alive | ha_state |
+--------------------------------------+------------------------+----------------+-------+----------+
| af482f32-9fd5-43e0-9403-fc49099c5434 | network-kilo.novalocal | True | :-) | |
