Re: vpls

Full mesh is the most commonly deployed architecture, but you can also have
a hub and spoke or partial mesh topology. Split horizon isn't enabled in
these cases. It's disabled on the hub in a hub and spoke topology as it's
loop free by definition. You must run STP over the backbone with a partial
mesh.
