  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.

  6. Changes -01 to -02 • Added section 5.1.8 on “Network Availability and Simplicity” • IGP Convergence • Per-Prefix LFA FRR • Hierarchical data plane and BGP Prefix Independent Convergence • BGP anycast • Applicability • Several editorial changes, fixed typos

  7. Moving Forward • Working Group Adoption • Add Multicast Support
