Hi all,


> The MPLS Network Actions (MNA) framework requires a method of indicating the presence of a Network Action and any Ancillary Data.
> 
> Is the consensus of the working group that we do this by:
> 
>  (1) allocating a new SPL for Network Action Indicators?
> 
>  (2) re-purposing the ELI SPL?
> 
>  (3) using some other method of indicating this such as making it an

(4) allocating a new SPL for a Network Action Sub-stack.


This is significantly different than (1) as NAI may not be part of the sub-stack and could be in the PSD.  And a solution may choose to have NAI and ISD in the sub-stack.

Yes, I am trying to be precise about definitions. No, I’m not a lawyer. Worse: I’m a mathematician. :-)
