OK.

OK. Good thinking...

Actually, this is up to the NOC operators.

In fact, the detection mechanism should go beyond protocol-level (RSVP 
and LDP) probing. All MPLS applications, such as L2-VPN/L3-VPN, should 
be able to check the connectivity of their circuits.

OK.

And, 6) We need more useful input like you have provided. :-)

Many thanks!
