I think that will never be fixed for Grizzly as that release is quite old.
Also, AFAIK, GRE requires OVS 1.10+ to work.

Title:
Network node port tags not reliably implementing
Status in OpenStack Neutron (virtual network service):
Won't Fix
Bug description:
I'm getting inconsistent implementations of port tags for router
internal interfaces and DHCP interfaces when they're created in OVS by
the Quantum OVS Plugin.
The resulting symptom is that when a new network/subnet is created
then either the instance is not able to get a DHCP address (this is
when the dhcp port isn't tagged) or the instance is unable to
communicate outside of its network (this is when the internal router
interface port isn't tagged).
Environment:
- Ubuntu 12.04.3 LTS
- Grizzly 2013.1.4-0ubuntu1~cloud0
- Quantum with GRE Tunneling
- OpenVSwitch 1.4.0-1ubuntu1.5
For example, what I should be seeing is something like this:
Port "tap7ef1ee95-52"
tag: 30
Interface "tap7ef1ee95-52"
type: internal
Port "qr-8bfc6675-3a"
tag: 13
Interface "qr-8bfc6675-3a"
type: internal
However, I end up seeing something like this:
Port "tap2b520e87-5e"
Interface "tap2b520e87-5e"
type: internal
Port "qr-ba0036f3-7e"
Interface "qr-ba0036f3-7e"
type: internal
It's not consistently happening - sometimes it actually is done
correctly.
The workaround to repair this is either to manually tag the interfaces
(which can be done if at least one of the ports on the subnet was
correctly tagged) or to restart 'quantum-plugin-openvswitch-agent',
which unfortunately causes a drop in connectivity for those which were
correctly tagged.
Has anyone else seen this?
Does anyone know of a bug fix or perhaps a better workaround?
