<p>If you choose to use vxlan for your tenant networks (the default
in OSA) you would probably be using a vlan for the external
provider network.</p>
<p>This would default to br-vlan, but alternatively can be any
interface of your choice. With the default configuration br-vlan
would need to be present on all of your controller (or dedicated
network) nodes and carry the tagged external vlan from your
upstream switches.<br>

<div>Hello.</div>

<div>I'm preparing to do my first deployment (of Yoga)
on real hardware. The documentation regarding br-vlan
was hard for me to understand. Could I get a
clarification on what to do with this? </div>

</div>
<div>Note: my intended use case is as an
academic/instructional environment. I'm thinking
along the lines of treating each student as a separate
tenant that would be preconfigured with templated set
of VMs appropriate to the course content.</div>
