John,

JD:  I agree with your point about PW labels, but doesn't the same point
apply to the label stack with two EOS bits?  Viz, having the EOS bit set
will not prevent an implementation from messing up the stack in
arbitrary and capricious ways.

Isn't another alternative to just have the MPLS TP network be completely
agnostic to the contents of its payloads, as a server layer is supposed
to be?
In that case, the payload could in fact be an MPLS payload with its own
stack.

AM> I must not have been clear enough, because that was my intention. We
are in agreement here. The payload would not have to be another MPLS
stack, but it could be, and that was the context of the original
discussion between Ben and Adrian.

Cheers,
Andy
