Hannes,

it's getting difficult to follow your reasoning because you switch from protocol details concerns (which have been addressed) to ietf procedures...

Can you clarify in a new thread what is your problem in making the Binding TLV _not_ MT aware in ISIS ?

Also, would you also suggest to make it _not_ MT aware in OSPF ? In such case we have to change the OSPF spec.
