I hadn't seen that particular draft before, but yes. Of course you'd probably also want to be able to configure IID based ACL's, static routes etc. where the prefix was auto-prepended to the static IID portion of the config. Don't want to hijack the thread, but I see no fundamental reason why your draft couldn't be combined with Fernando's work. -------------------------------------------------------------------- IETF IPv6 working group mailing list ipv6@ietf.org Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
