I would like to implement the above, but it is somewhat hard when there is no assigned type code from IANA. What does it require for IANA to assign a type code? (same goes with the preferred route option).
In my view the router solicitation could be viewed as "service solicitation", and in addition to normal routers answering with prefixes, some other "services" could send their own replies with their own options (like the DNS address), but without prefix information. Of course, single router box can do all answering, if desired. -------------------------------------------------------------------- IETF IPv6 working group mailing list [EMAIL PROTECTED] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
