draft-leymann-mpls-seamless-mpls-02 • Architecture • Changes • Moving Forward
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.
