Hmmm. Interesting, and opens rather a can of worms. By the way, linux-2.4.18/net/core/neighbour.c:neigh_update() seems (at a quick glance) to go with the "don't do anything if override = 0" interpretation, but then that's a whole _different_ can of worms! Most folks back in 1999 seem to have gone with the REACHABLE->STALE interpretation though ... unless there's a canonical 2461bis which fixes this problem I'm going to interpret it as a MAY, eg nodes may or may not reset the entry. Thanks everyone for your comments. I'm going to fix the draft up a bit for -01, I think getting some kind of Optimistic DAD standardized is going to be essential for Mobile IPv6 to be useful ... -----Nick -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
