According to the default rule, all three are in the same subnet-local zone. You've just chosen for some reason not to advertise some prefixes on some links. Personally, I'd put this in the category of "don't do that", just like I wouldn't recommend using using different subnet ids for different prefixes on the same link. -Dave -------------------------------------------------------------------- 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] --------------------------------------------------------------------
