[c-nsp] MPLS down to the CPE

I'm sorry I should have made myself clear on this, I meant Inter-AS MPLS
where one ISP owns all ASNs
Otherwise yes I agree, optA is the only solution, so far..

Gaah I meant to write OptB. OptC I saw no point ever, full-trust needed and
only thing you really might save is SPF complexity, which isn't deciding
factor in convergence anyhow.

I've never seen anything but OptA in inter-AS MPLS NNI. OptB would be great,
but as per previous mail, lack of security excludes it. OptC I've only seen
in shops doing BGP confed et (euch).
