Hey Aaron,

Correct.

Correct.

Why do you prefer to dynamically start PtP LDP for pseudowires,
instead of just using the existing BGP session? Particularly if you
already offer VPLS product, why do you insist provisioning two
entirely different stacks? Programmatically it's very complicated,
programmatically speaking your best option would be to provision
point-to-point pseudowires as VPLS with two points and MAC learning
disabled having lowest overall complexity possible.
The LDP argument might make sense, in an environment where you do not
need BGP at the edge at all. Otherwise, I think it is just not
justifiable.
