Public bug reported:
When a router is migrated between DVR+HA and HA(i.e DVR+HA->HA and
HA->DVR+HA), redundant "network:router_ha_interface" ports are created.
To reproduce the issue(2 node setup with "dvr" and "dvr-snat" modes is
sufficient), create a router
dr1 in DVR+HA mode. Then repeatedly flip this router's DVR+HA and HA flags.
You can see redundant "network:router_ha_interface" ports.
I have a 2 node devstack setup, 1st l3-agent in "dvr" mode and 2nd one in
"dvr-snat" mode.
Whenever HA flag is set to router, port with device_owner
"network:router_ha_interface" should be created for only 2nd node i.e l3 agent
with "dvr-snat" mode.
Steps to reproduce:
1) create a network n1, and subnet on this network with name sn1
2) create a DVR+HA router(with name 'dr1'), attach it to sn1 through router
interface add and set gateway(router-gateway-set public)
3) boot a vm on n1 and associate a floating ip
4) set admin-state to False i.e neutron router-update --admin-state-up False dr1
5) Now update the router to HA i.e
neutron router-update --distributed=False --ha=True <router-id>
set admin-state to True
6) There will be two "network:router_ha_interface" ports, though one will be
used by qrouter-xx namespace
7_ Again update router to DVR+HA
8) There will be three "network:router_ha_interface" ports, though one will be
used by snat-xx namespace
I observed the "network:router_ha_interface" port first created will
always be used by qrouter-xx(when router is HA) and snat-xx(when router
is DVR+HA) and later created ports are never used.
