Thanks a lot Acee/Alexander/pushpasis & Joel for answering our query.

Since the idea of having service label as top label is breaking MPLS/SR architecture we don't want to proceed with that idea.
We just hoped this would reduce label stack size :)

Thank you all so much for your time.

​Hey Acee,
​

In MPLS, one label is like any other label (except for the first 15 which are reserved). I think you are missing a whole lot of context here - you can’t just declare a new label type with different semantics.


​That is actually quite incorrect :)  We do declare new semantics for labels all the time ... ​

Few examples:

- context label
- entropy label
- sr label
etc...

​Cheers,
R​
