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 specification, but only for IPVPN and EVPN families.
