When the tenant creates the first HA router-1, neutron will try to create HA network for this project.
But during the HA network creation procedure, we assume it has 2 steps:
(1) create HA network
(2) create subnet for this HA network
another router-2 creation API call is comming, while HA network creation is just done the step (1),
this API can retrieve the project HA network, and the HA network has no subnet.
Because of the
"[Open Discussion] neutron can create port from network which has no subnet"
https://bugs.launchpad.net/neutron/+bug/2016197,
router-2 will create HA ports without fixed IP.
So this HA router-2 will not get UP forever in L3 agent side.
In our production environment, we see many times of such issue. |
