Hi,
In section 4.2 of RFC 2461 regarding the RA message format the following
is mentioned
Reserved A 6-bit unused field. It MUST be initialized to
zero by the sender and MUST be ignored by the
receiver.
The mobile-ipv6 draft draft-ietf-mobileip-ipv6-24.txt mandates using the
most significant bit of this field as a home agent bit(will be set to 1 if
the router is also a MIPv6 HA on this link). I do not know what is the
best way to solve this apparent contradiction. I see the following
possible solutions (in no particular order)
* Reduce the reserved field length in RFC2461bis to 5 bits
* Change the MUSTs to SHOULDs in RFC2461bis
* Put a note on RFC2461/RFC2461bis in the rfc-index saying it has been
updated by the MIPv6 RFC(when it comes out)
Regards
Suresh
