1 Seamless MPLS draft-leymann-mpls-seamless-mpls-02.txt Nicolai Leymann, Thomas Beckhaus (DT) Wim Henderickx (Alcatel-Lucent) Clarence Filsfils (Cisco) Dirk Steinberg (Steinberg Consulting) Bruno Decraene (FT) 79th IETF, Beijing, China

2 draft-leymann-mpls-seamless- mpls-02 Architecture Changes Moving Forward

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.

4 Architecture AGS DSLAM ABR AGS DSLAM ISIS Level 2 ISIS Level 1 static static default NH self NH unchanged LDP LDP Downstream on Demand LDP DoD Labeled BGP Routing Label Distribution Seamless MPLS

5 Use Cases PW for Business P2P Service Core Network Use Case #1 Redundancy in the access AN Service Creation for Residential Customers AN PW towards SC for RC AGN ABR

6 Changes -01 to -02 Added section 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
