<p>I have not tested the GRE tunnel, I used geneve Tunnel, I think
they are similar.<br>
</p>
I mean that the tunnel encap ip uses the ovs bridge.<br>
<br>
What is your tunnel source ip? Your source IP should be configured
on an ovs bridge, the physical out of this bridge uses dpdk<br>

<pre wrap="">sorry to overlook.
from your configuration, you have two bridges, one is with dpdk, and
the other is not which is on management subnet, right?
can you share the GRE tunnel command for reference?

I guess your package sent to the userspace from vm by dpdk , and then
through the tunnel to return to the kernel.
I do not know if this will be a problem.
I suggest you can try your management interface using OVS bridge with dpdk,
such as "g1".

thank for your reply.
the 192.1.2.159 is actually on the same subnet of the management
interface, it is not part of the OVS bridge.

I think you may have caught the tunnel inner package.
Is the tunnel outbound from interface dpdk0? how about caught dpdk0 with
mirror?
Or use dpdk-pdump?

<pre wrap="">Hi
How do I configure mirroring of all traffic to a GRE tunnel on OVS+DPDK?
I have a OVS+DPDK setip as below.

I tried to create gre tunnel for packet mirroring
#ovs-vsctl add-port g1 gre0 -- set interface gre0 type=gre
options:remote_ip=192.1.2.159 -- --id=@p get port gre0 -- --id=@m
create mirror name=m0 select-all=true output-port=@p -- set bridge g1
mirrors=@m
I cannot find any packet arrive on 192.1.2.159, any idea?
I have tried to use the same command in an OVS setup without DPDK
enabled, it works.
please help
