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.
