Hi Shahram, Just one comment. >I would also argue that LSPs can't have UP-MEPs, since PWs from many ingress ports can enter an LSP and therefore the LSP can't start on the ingress interface. I think this depends on implementations. Any RFC don't restrict to DOWN-MEPs in an LSP. Anyway, MEP mechanism is out of scope in this draft as you said. Thanks, Hideki Endo >Hi, > >Although I mentioned I am Ok with the draft to be advanced to RFC, but after reviewing it in more details it appears that the draft, in spite of its name, does talk about UP-MEP at all and only talks about UP-MIP, while the figures show UP-MEPs for LSPs. Even if the scope of the draft is UP-MIP, considering that there can't be a MIP without a MEP, the draft should have some wording regarding UP-MEPs and their applicability to LSPs and PWs. I would also argue that LSPs can't have UP-MEPs, since PWs from many ingress ports can enter an LSP and therefore the LSP can't start on the ingress interface. > >A quick fix at this point is to mention UP-MEP is out of scope and change the figures to only show Down-MEPs.
