Unformatted text preview: tets in binary of an IEEE identifier are as follows: 0 00 11 2 |0 78 56 3| +----+----+----+----+----+----+ |cccc|ccug|cccc|cccc|cccc|cccc| +----+----+----+----+----+----+ written in Internet standard bit-order, where "u" is the universal/local bit, "g" is the individual/group bit, and "c" is the bits of the company_id. 64 Format Appendix A, "Creating Modified EUI- Interface Identifiers", provides examples on the creation of Modified EUI-64 format-based interface identifiers. The motivation for inverting the "u" bit when forming an interface identifier is to make it easy for system administrators to hand configure non-global identifiers when hardware tokens are not available. and This is expected to be the case for serial links tunnel end-points, for example. been for The alternative would have these to be of the form 0200:0:0:1, 0200:0:0:2, etc., instead of the much simpler 0:0:0:1, 0:0:0:2, etc. IPv6 nodes are not required to validate that interface identifiers created with modified EUI-64 tokens w...
