Hello,
I have ovs bridges SW-00 and SW-01 operating in their respective
docker containers as following
-------------Container A--------------

/-----------------------------------------------------
So the two containers are connected via VETH pair and can ping.
However the VXLAN traffic is not passing any traffic; the packets are
hitting the rule on SW-00, however they are not making it to SW-01.
ovs-appctl ofproto/trace SW-00 in_port=10
Flow:

bridge("SW-00")
---------------
0. in_port=10, priority 10
output:2
-> output to native tunnel
>> native tunnel routing failed
Final flow: unchanged
Megaflow:

ovs-appctl ovs/route/show

Cached: 0.0.0.0/0 dev eth0 GW 172.17.0.1 SRC 172.17.0.2
The ofproto trace reports "native tunnel routing failed", despite
there exists an appropriate entry in ovs/route/show. I'd appreciate
any input on why this could be happening.
Regards,
Alan
