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).
