I could probably piece together an answer by going way back in the mail archives but...
The "Default Address Selection for IPv6" draft's source address selection seems to prefer addresses of appropriate scope over "preferred" or non-deprecated addresses. What is the reasoning behind that? For example, a system has one interface configured with a deprecated site-local address and a non-deprecated global address. When communicating with a site-local destination, the draft specifies that the deprecated site-local source address would be used instead of the global address. According to the addressing architecture, "A deprecated address should be used only by applications that have been using it and would have difficulty switching to another address without a service disruption." I don't believe applications would have much difficulty switching to the global address to communicate with site-local destinations in the above example. -Seb -------------------------------------------------------------------- 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] --------------------------------------------------------------------
