I just read this draft and I think it's an implementation of the draft [I-D.zhou-ippm-enhanced-alternate-marking], which discusses the method of encapsulating the enhanced alternate marking header in IPv6. I have several comments.


  1.  It doesn't cover the encapsulation on SRv6 yet and I think a solution for SRv6 would be more useful.
  2.  More deployment consideration discussion should be given when it's encapsulated in HBH EH
  3.  The document mentioned two PBT modes discussed in [I-D.song-ippm-postcard-based-telemetry]. Since the PBT-I variation has been merged in another draft [I-D.ioamteam-ippm-ioam-direct-export], this draft may need to be updated accordingly.

Thanks!

Haoyu
