I seem to be having an issue with getting openvswitch configured properly. I am able to setup the OVS bridges br-tun and br-int with no issue and I can ping both the local IP (10.0.2.22) and the other vxlan endpoint (10.0.2.35) with no issue. However once I start the agent the IPs stop responding. The only way I can recover is to stop the agent and remove/readd br-tun.

When I start the agent the vxlan tunnel is created does not seem to work. The other end is a Centos 7.2 Liberty setup and I have successfully run another Centos 7.2 compute node using OVS and vxlan...

Here is the ovs-vsctl show:

        Port br-int
            Interface br-int
                type: internal

I'm not sure how to continue to debug this...


Here is the OVS config:
