Open Stack

Your configuration looks correct, and provider networks are what you need
for implementing this use case.

Is the traffic for your subnets improperly tagged, or are you unable at all
to forward traffic?
If you're not using GRE overlays it might make sense verifying that VLAN
108/109 are allowed on physical switch ports or that the physical switch
ports are in trunk mode.
