I am unable to get external vlans working on liberty with openvswitch ml2 mechanism

asked 2015-11-23 13:17:22 -0600

I'm running into a problem. and I am sure i am missing something basic. I have a gist of all the details found here https://gist.github.com/whytewolf/510ba641b28c497b8caf (the gist)

but the TL;DR is I have 3 vlans for my external network, and 10 for my internal. because it all goes through a single port i used ovs to separate the external and internal vlans. and this works. if I ping from outside i can see the arp requests going up to my external ovs br. however that tagged traffic does not make it into br-int. or to the router. and if i try to ping from the router I do not see the traffic except in the local port in the router. and there it is not tagged with the vlan.

this is a setup i had working in icehouse,juno and kilo. but i can not seem to get it to work in liberty. I have been pouring over the documentation for 3 days now trying to see what i am missing. and at this point i am sure it is something stupid and simple.

Was external network provider been used to create external vlans ?

actually i found my issue last night and was to tired to post what the issue turned out to be.

I messed up a setting in ml2_conf.ini I had mechanism = openvswitch instead of mechanism_drivers = openvswitch

so neutron-server had no way of knowing how to bind the ports. so the openvswitch agent was not able to tag them correctly.
