Re: [mpls] Comments on draft-bocci-mpls-miad-adi-requirements

Hi Tony,
I think that the situation with an arbitrary LSR imposing ADIs is more
nuanced as we must understand where the particular ADI must be disposed of.
I am not certain how it, for example, applies to SR-MPLS. I can imagine
hierarchical LSP imposed between two adjacent SR nodes. If that is the
case, imposed ADIs must be disposed within that segment. Please let me know
if I'm missing anything.

Regards,
Greg
