[OPSEC]Re: [Technical Errata Reported] RFC7707 (8119)

[Bob Hinden <[e-mail]>]

Hi,

I don’t think this errata is correct.   Looking at RFC4291 "Appendix A: Creating Modified EUI-64 Format Interface Identifiers” the bits in IEEE EUI-64 Identifiers are numbered starting from 00.  

   The only change needed to transform an IEEE EUI-64 identifier to an
   interface identifier is to invert the "u" (universal/local) bit.  An
   example is a globally unique IEEE EUI-64 identifier of the form:

   |0              1|1              3|3              4|4              6|
   |0              5|6              1|2              7|8              3|
   +----------------+----------------+----------------+----------------+
   |cccccc0gcccccccc|ccccccccmmmmmmmm|mmmmmmmmmmmmmmmm|mmmmmmmmmmmmmmmm|
   +----------------+----------------+----------------+----------------+

The original text is correct.

Bob
