Dave, Jan, Andrew,

An interesting draft. I have a few comments, with my WG chair hat off:

1. An editorial comment, there's no "-" or internal uppercase "W" in
"Pseudowire", which is the proper spelling (I saw at least three
different spellings in the draft).

2. Section 1.3 states: "PWs are
   configured as bi-directional paths over the MPLS-TP network, usually
   by an external management platform.  At present no open standards
   exist to provision these PWs, and therefore there is a reliance on
   vendor specific provisioning platforms."

Certainly, there's nothing that prevents the use of T-LDP for PW use
in MPLS-TP networks, this is already documented in section 5.2 of RFC
6373.

Speaking of which, you should also have a table in your draft similar
to the table in section 5.2 that shows how your draft meets the
MPLS-TP control plane requirements listed in section 2 of RFC 6373.

You may also wish to read draft-cao-pwe3-mpls-tp-pw-over-bidir-lsp,
which specifies useful functionality in this area.

In any case, you should be clear that this is an alternative control
plane to T-LDP.

3. Section 4: In addition to RFC 6423, you may wish to include a
reference to draft-ietf-pwe3-vccv-for-gal, which defines the VCCV mode
for use with MPLS-TP. You may also wish to reference RFC 5860.

Cheers,
Andy
