Assuming that one suspends disbelief about the whole multi-link subnet thing in the first place, it's far from obvious to me that unnumbered links aren't part of a subnet that exists on other links. The most common use I've seen of proxy ARP in IPv4 has been to extrude small numbers of IP addresses across PPP links. My apologies for not answering the rest of Steve's message right now, but my family is about to break down the door to my office because they want to eat dinner now.... -------------------------------------------------------------------- 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] --------------------------------------------------------------------
