I don't understand the rationale for this work either. the first PD proposal (by Brian Haberman) was indeed based on using ICMP as transport. separate message types instead of piggy-backing on RS/RA though. as we continued to develop that mechanism we realised that we were pretty much reinventing the DHCP protocol machine. that realisation led to specifying it as an DHCP option instead of as a new protocol.
a technical comment on your proposal; how do you plan to support shared links with multiple requesting routers? RAs are typically multicast. /ot -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
