Re: [mpls] Taxonomy of MPLS MNA drafts

Hi Robert,

A set of numbers can contain only one element.  

In fact, most solutions are proposing using only a single sub-stack for the common cases. I don’t think I’ve seen anything that proposes multiple sub-stacks until we start talking about trying to address multiple scopes.
