Thanks. > I'll provide my detailed comments separately; the substance, though, is > that: > - we need to refine the Hop limit text as you point out After some discussion with Carsten, it seems that we may need both bits for Hop Limit compression. Current idea now is that 1-bit indicates compression, another bit indicates whether the elided Hop Limit is 63 or 1. I originally thought we could do egress filtering based on the destination address, but Carsten thought that it missed the point of the Hop Limit. The cost is we utilize the reserved bit in the IPHC encoding and remove any flexibility it could have provided. > - we should be able to extend the concept of common prefix compress > global addresses that result from states without being specific on how > the addresses are passed on, which I understand is another charter item.
