Hi folks,
I have a DVR-enabled cluster made of a controller, network, and compute
node. The *agent_mode* is set as *dvr_snat* on the network node, and *dvr*
on the compute node. The north-south traffic works in both SNAT and the
floating IP scenarios, but I cannot explain the extra interface shown up in
the Horizon dashboard for every tenant router. More details as below:
*ip netns* output on the compute node:

*ip addr show* from within the router namespace on the compute node:
[image: image.png]
*Notice there is only *one* *qr* interface, the gateway, for the tenant
subnet.
Here is the display from the Horizon dashboard router interface page:

Do you see the extra interface (*da7884d9-2ff1*)? The only place I can find
it is from inside the additional routing table in the router namespace:

What does that extra interface come from and what is it for? Why does it
show up in the dashboard, but not in the command line output?
Thank you all in advance.
