ietf-65 draft-kulmala-l3vpn-interas-option-d-02.txt Draft Overview and History 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 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.
