Abstract:
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 1, 128 and EVPN IP
Prefix routes, and therefore this document updates [RFC4271].
