Public bug reported:
When deleting a Router, there are ERROR logs of failed unplugging ha
interface. This happens in environment with stable/mitaka. What needs
to note is that router could be deleted successfully after the ERROR.
Reproduce steps:
neutron router-create test
neutron router-delete test
monitor log in neutron-l3-agent.log
This problem is different from existing defects. some existing defect
addressed problem of looping deleting router. some addressed problem of
race between router sync and router deleting. And some defect has
similar symptom which happened on different place, such as bug 1606801.
