Hi, I am currently working on my Neutron docs for DevStack[1], and realized that there is some common pieces between provider networking API extension and the l3 networking API extension. In both cases, the administrator is directed to manually create a bridge device and add the physical interface to it[2]. I have a patch into DevStack that does this in the provider networking case[3] - and a Vagrant setup I use for the l3 networking extension has a puppet recipie that automatically adds the public interface to the bridge after DevStack runs[4]. Should we have DevStack go ahead and wire up the bridge and interface when using the L3 agent?
