3 draft-leymann-mpls-seamless-mpls-02
Describes a scalable architecture To use MPLS in a large (100k nodes) AS splitted across IGP areas. Based on existing IETF protocols. No new protocols extensions. Provides end to end transport MPLS possible between any nodes  no need for service specific configuration on intermediate transport nodes.
