Hi Ron,

I think the same SID£¬such as you mention, May be included in different SRH of different packets, so the same SID have different behavior in different packet whose SRH include it.


Cheers!

Folks,

Are there use cases for the following functions:


  *   0x001F ¨C END with PSP, USP and USD
  *   0x0023 ¨C END.X with PSP, USP and USD
  *   0x0027 - END.X with PSP, USP and USD

It seems that if the SRH was removed at the penultimate segment, there is little sense in removing it again at the ultimate segment.

                                                                                                                             Ron
