Hi Manav, I don't think I fully understand and need some clarification. See in line.

What if we have a non-1588aware LSR in the path? [Lizhong] All the LSRs and LERs along PTP LSP MUST be 1588aware, right? >The head end > when setting up the RSVP path would know this (by inspecting the IS- > IS or OSPF TE info) and could in such cases make use of the Entropy > label to ensure that all PTP packets follow the same path. [Lizhong] How to use entropy label to ensure all PTP packets follow the same path? If there is entropy label, it is possible that the forward and reverse path would be different. >This is > one scenario where i think we may want to use Entropy labels. > > Cheers, Manav > > From: [email protected] [mailto:[email protected]] > Sent: Tuesday, January 18, 2011 6.03 PM > To: Bhatia, Manav (Manav) > Cc: [email protected] > Subject: Re: [TICTOC] Transporting PTP messages (1588) over MPLS Networks > > Hi Manav, > In section 8 ECMP, since it is said PTP LSPs and PWs MUST NOT be > subject to ECMP, why in section 5.2 the encapsulation of figure 2 > has entroy label?
