Internet-Draft draft-ietf-bess-evpn-ipvpn-interworking-10.txt is now available. It is a work item of the BGP Enabled ServiceS (BESS) WG of the IETF. Title: EVPN Interworking with IPVPN Authors: J. Rabadan A. Sajassi E. Rosen J. Drake W. Lin J. Uttaro A. Simpson Name: draft-ietf-bess-evpn-ipvpn-interworking-10.txt Pages: 33 Dates: 2024-04-11 Abstract: Ethernet Virtual Private Network (EVPN) is used as a unified control plane for tenant network intra and inter-subnet forwarding. When a tenant network spans not only EVPN domains but also domains where BGP VPN-IP or IP families provide inter-subnet forwarding, there is a need to specify the interworking aspects between BGP domains of type EVPN, VPN-IP and IP, so that the end to end tenant connectivity can be accomplished. This document specifies how EVPN interworks with VPN-IPv4/VPN-IPv6 and IPv4/IPv6 BGP families for inter-subnet forwarding. The document also addresses the interconnect of EVPN domains for Inter-Subnet Forwarding routes. In addition, this specification defines a new BGP Path Attribute called D-PATH (Domain PATH) that protects gateways against control plane loops. D-PATH modifies the BGP best path selection for multiprotocol BGP routes of SAFI 128 and EVPN IP Prefix routes, and therefore this document updates the BGP best path selection in [RFC4271], but only for IPVPN and EVPN families.
