[PWE3] Question on draft-boutros-pwe3-mpls-tp-ms-pw-01

[Greg Mirsky <[e-mail]>]

Dear Authors,
I have a question on Section 3.1.2.1 when Lock (LI) is sent to S-PE.
According to draft-ietf-mpls-tp-li-lb-01 Lock operates only on MEP, i.e. it
originated by MEP and addressed to MEP. In scenario considered in 3.1.2.1 LI
addressed and processed by S-PE which is a MIP, not MEP. I believe that if
Loopback to be performed on MS-PW the LI request must be send to remote
T-PE. LB then might be set on S-PE or remote T-PE if LI was successful.
And I think that referring to nodes as T-PE and S-PE when LI-LB performed on
MPLS-TP LSP is confusing. To address PE a PW label must be present which is
not the case if scope of LI-LB is the LSP.

Regards,
Greg
