No open reviews found in this bug, unassigning. Please add a comment with active reviews before assigning an individual, or tag the bug in the gerrit review, which will do that automatically. We try not to assign bugs without patches as that discourages other folks from looking into bugs.

[Dr. Jens Harbott (j-harbott)]

By default devstack sets up Neutron only with the local network type, please look at the neutron docs for enabling vlan type.
