I've heard this argument that site-local addresses somehow make the site border router filtering problem easier, and I don't get it. As far as I can tell, they don't help at all, and in fact just make the problem a little worse. I have to filter all the kinds of addresess that shouldn't be crossing my router anyway (eg, ingress filtering, various whacky combinations of transition address spaces with various kinds of IPv4 addresses, etc), whether applications in my site are using site-local addresses or not. Site-local addresses are just one more flipping thing I have to filter.
So how were site-local addresess helping me with this problem again? -------------------------------------------------------------------- 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] --------------------------------------------------------------------
