I have to disagree with the premises of this statement, if not the
conclusion. This change does indeed change the semantics of the
implementation, and also the value of the bytes on the wire. The
InterfaceIndex and the Ipv6IfIndex are two different numbering schemes,
and replacing the latter with the former forces changes in all
implementations. Cf discussion on the IPv6 Design Team homepage
<http://www.ibr.cs.tu-bs.de/ietf/ipv6mib-dt>.
Unfortunately that discussion never reached a conclusion, so the MLD-MIB
designers do not really have any guidance in the choice between the two
schemes. Say, if the design team had concluded to do away with the
Ipv6IfIndex in the IPV6-MIB and friends, the MLD-MIB should of course do
the same.
>From my own position, the proposed change does not hurt, for I have not
completed the implementation of the MLD-MIB. But anyone with a working
implementation of MLD-MIB will have to modify code to adapt to this
change.
