Re: I-D Action: draft-sarikaya-6man-sadr-overview-07.txt

The source address based routing issue has been hanging around here for quite while. In this WG alone we have two competing approaches to it, both based on ICMPv6 options. To see what other WGs are working on would be good to get the general overview, maybe Prague is a good time to understand the bigger picture.
