In that particular case, the source address selection algorithm isn't applicable. There are a number of such cases where RFCs specify a specific source address to use for specific packets (echo replies are another example), and where source address selection doesn't occur. Your general concern is valid, though. -Seb -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
