Hi Robert,

​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…

But the mechanisms for advertising the label semantics as such must be specified as well.

Thanks,
Acee



​Cheers,
R​
