In your previous mail you wrote: The current draft states that a non-zero label could be changed by an intermediate node to a non-zero value. However, during the discussion on the topic in SLC it was concluded (IMO) that this is undesirable, and it would be more useful (and sound) to keep the value always immutable (end-to-end). => I disagree: if the end node is too dumb to set itself the label (i.e. just uses in any case the zero value) and the first router for instance sets the label when needed then the zero value should not be immutable. I don't use dumb hosts (:-) but it seems this kind of things already commonly happens for RSVP in the real world so we should keep the door open... So I fully share Robert Elz's opinion.
AH: It could be possible to change AH, but it might not be worth it. => Robert Elz has just explained why we must not change AH... And it seems you don't understand that AH can't really help to protect something in transit, i.e. intermediate routers have not the key and can't verify the AH MAC.
