Sorry - missed the mpls-tp list by mistake.

Malcolm,

Just a couple of remarks picking up from a point of Neils.

In section 6.5 "The MPLS-TP NE MUST support the configuration of
maintenance entity identifiers (e.g. MEP ID and MIP ID) for the purpose
of LSP connectivity checking."

As the document is specifying eventual requirements for a protocol, this
sentence presupposes a field to carry the identifiers being specified
here, so seems to be about how the requirements in [3] are to be
implemented.

It seems better to me to remove this sentence and to expand the first
sentence of sect 6.5 to allow for additional configurable items to arise
during further work on implementations.

"The MPLS-TP NE MUST provide the capability to configure the OAM
entities and functions specified in [3], as well as any additional items
arising during implemention of those requirements."

This reworded sentence now also covers the reference to identifiers in
the last paragraph "The connectivity check process of the MPLS-TP NE
MUST support provisioning of the identifiers to be transmitted and the
expected identifiers."

That sentence can also be removed. If implementation work decides that
additional identifiers are needed, then the reworded first requirement
states that those identifiers must be configurable

Thanks,

    George
