it shouldn't. in 7596 it states that the IID is created as specified in 7597. that 7598 uses a different on-the-wire format doesn't change that. in MAP data packets those bits are again represented in a different bit position. >> I agree with Ole.

I don't know, but just a point to the IID generation, it must be a consistent method used across the domain (in algorithmic mapping), but in LW46 it could pretty much be anything you like, if you have a way to coordinate that between the BR and CEs.
