Peter,

How does this fit with the comment in section 7 > "PDELAY_REQ and PDELAY_RESP are exchanged between adjacent PTP clocks (i.e. > Master, Slave, Boundary, or Transparent) and MAY be transported over > single hop PTP LSPs.". > > Would it be correct to say that for PTP messages exchanged between > peer-delay BC and peer-delay BC within LSRs, that a single hop PTP LSP would > be used? I think this Yes, i think this is correct. > is related to section 1 where peer-to-peer boundary clocks are not listed > (some folks think this mode is supported in IEEE 1588-2008, although not > explicitly defined).
