Re: [mpls] Poll on draft-koike-mpls-tp-temporal-hitless-psm

Hello Fei,

Thank you for your comment.

This description is based on MPLS=TP OAM requirements specified in 
section 2.2.11 and 2.2.12 of RFC5860. We will add the following 
information in the sentence for clarification when updating the draft, 
if this works for you.

"... because these functions are supported only between end points of a 
transport path according to RFC5860."

Best regards,

Yoshinori
