multinode neutron vxlan traffic not flolwing between vm and router.

I have installed a multinode Juno config using RDO.

I am using VXLAN tunneling between 2 compute nodes to a neutron network node. I can see arp traffic going from the VM to the router and from the VM to the dhcp server but no other traffic seems to be flowing.

If I try to ping from the router to the vm I can see the pings going out the router interface and getting to the tunnel and comming out of the tunnel on the other side but the traffic does not get from the tunnel in the compute node to the actual tap interface on connected to the VM.

I have had a similar configuration working with RDO and Icehouse but with GRE.

Please, post :

ovs-vsctl show ( on both network node && compute node)

It turns out that the magic encantation was to downgrade the neutron RPMs I found a redhat bug 1163754 that seems to have fixed this problem up.

In meantime downgrading like

 yum downgrade openstack-neutron\* python-neutron

is not a solution.

Are you saying that python-neutronclient is actually the only broken rpm?

I am saying that per
openstack-neutron-2014.2-9.el7 is fixed. Mentioned bug is not about python-neutronclient.
