Because when you receive a ND packet with a hopcount != 255 you know for sure that the packet has been routed over one hop, while ND packets should only be on the same link. If ND packets would be checked for being eg 1, I could set the hopcount to 5 when I am 4 hops away and successfully send you Router Advertisements and other things, would not be good would it :) Folks doing BGP are also starting to do this for the anti-spoofing effect that it has. See the RFC's or one of various good books on this. Greets, Jeroen
