I'm looking for what a network operator would consider a realistic reference deployment of MPLS within the metro area network. 

By "realistic reference", I'm asking about what a network operator would consider to be a typical, perhaps most common, application of MPLS technology.

From a bookish perspective, I understand MPLS well but have never implemented it in the scope of my current field of study (metro area networks). I would dearly like to get this "grounded" perspective from anyone who might care to share it.

Cheers,

Etienne
