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.
