[Bug 1405528] [NEW] Migration of legacy router to distributed router should remove the original gateway port

 

Public bug reported:

In the case of update legacy router to distributed router, if hosting to
the same node, qg port can not be added to snat router because it have
not been removed from original centralized router, otherwise, qg port
remains in the original centralized router.  I think original qg port
should be removed when updating the legacy router to distributed router.

operation defined as follow:
neutron router-create dvr
neutron router-gateway-set dvr ext-net

neutron router-interface-add dvr vxlan-subnet1

neutron router-update dvr --distributed=true

we can find  qg port is still in qrouter after updating operation.
