I disagree that DHCPv6 too heavy-weight (whatever that means). Haberman's ICMP prefix delegation draft initiated the IPv6 W.G's work on prefix delegation. it pretty soon became clear that we were reinventing DHCP, so instead of developing a new DHCP lookalike, we decided to reuse the existing DHCP infrastructure instead. if I understand you correctly you want to specify a separate protocol which handles prefix delegation in a restricted setup. how is the requesting router going to determine which prefix delegation protocol to use? can you auto-detect that the user setup is suitable for the 'simple' protocol? as an implementor I find that implementing only one protocol to solve a problem is less complex and results in a less heavyweight implementation, than having to implement two protocols... /ot -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
