Network+ Deluxe Study Guide 2nd Ed. Errata - N10-005

Exam Objective 1.2 mentions EUI-64.

I could not find anything in the book that taught me what this is so looked it up. On page 98 there is a diagram of an ethernet address using MAC-48.

To explain to my future students what EUI-64 is I would find it useful to discuss a simple conversion from MAC-48 to EUI-64. But the diagram in the book places the I/G and G/L bits at the front (left side) of the OUI 24-bit block.

RFC 4291 and 5342 indicate that the G/L or U bit (universal bit) is bit 7 reading from left to right of the OUI.

Have I miss understood this or is the diagram incorrect.

Thank you,
