  2. Draft Overview and History ABSTRACT This option combines per VPN VRFs at the Autonomous System Border Router (ASBR) as described in 'Option A' with the redistribution of labeled VPN-IPv4 routes as described in 'Option B'. In addition, this option allows for a data plane consisting of two methods of traffic forwarding between attached ASBR pairs. Combination of Multi-AS options ‘a’ and ‘b’, targeted at Multi-AS MPLS IP VPN (RFC 4364) service extensions. • MP-eBGP peering between ASBRs • ASBR has a minimum of a VRF per VPN • Hierarchical per-VPN admission control at the AS border • Allows VPN topology hiding, traffic load balancing, path optimization, route summarization, route capping etc. • Trust model of Option B remained – specifically MPLS based data plane –addressed in this draft • Added new authors draft-kulmala-l3vpn-interas-option-d-02.txt

  5. What is covered in this Draft? Updated the following sections: • Reference Model • Operation section • Deployment Considerations • Comparison of current RFC 4364 Multi-AS options • Security section draft-kulmala-l3vpn-interas-option-d-02.txt draft-kulmala-l3vpn-interas-option-d-02.txt

  6. Next steps • More discussion on the list – particularity from Service Providers wanting to partner at Layer 3 • Adopt the ID as a WG Document draft-kulmala-l3vpn-interas-option-d-02.txt draft-kulmala-l3vpn-interas-option-d-02.txt
