In your previous mail you wrote: I have two inter-related issues which are unclear to me in RFC 2460. Would anyone please clear these ambiguities? 1: If the sending node doesn't include any Hop-by-Hop option header can intermediate router inject Hop-by-hop options? => no, it MUST NOT.
2: If there is Hop-by-Hop option header present can intermediate router add any new option or modify existing options? => it MUST NOT add any new option but it MAY modify an existing option if the option is marked as mutable en route (there is a bit in the type to recognize such options) and only in the way defined for this option. Note there is no such option registered by IANA today so it is hard to give a real example... Regards [EMAIL PROTECTED] PS: look at the AH specs (RFC 2402 and I-Ds) for mutable fields in headers. -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
