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.
