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.
