Ali:

Hi!

RFC7385 already defines an Experimental range, why do we need another one?  Same question about reserving 0x7F (if rfc7385 already reserved 0xFF).

One of the reasons I’m asking is because if you’re only changing the 0x0C – 0xFA range, which is currently unassigned, the you (1) only need to include those values in this document, and (2) you don’t need to Update rfc7385:

Thanks!

Alvaro.

Hi Alvaro,

You’re right. I had some holes in my assignment. Following should fix it.

   Value MeaningReference
   0x0C-0x7A Unassigned
   0x7B-0x7E Experimentalthis document
   0x7F Reservedthis document
   0x80-0xFA Reserved for Composite tunnelthis document
   0xFB-0xFE Experimental RFC7385]
   0xFF Reserved[RFC7385]

Thanks,
Ali

Ali:

Hi!

So, you’re really only changing the 0x0C – 0xFA range, right?

If my hex is not wrong, you’re missing some pieces below: 0x40-0x7F, and 0xC0-0xCF, which I’m assume remain Unassigned, right?

Thanks!

Alvaro.
