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.

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.
