Abstract:

   Ethernet Virtual Private Network (EVPN) provides a unified BGP
   control plane for both intra- and inter-subnet forwarding within
   tenant networks.  When a tenant network spans multiple domains —
   including EVPN domains as well as domains that use BGP VPN-IP or IP
   address families for inter-subnet forwarding — it becomes necessary
   to define the interworking mechanisms among these BGP domains (EVPN,
   VPN-IP, and IP) to ensure seamless end-to-end tenant connectivity.

   In addition, this document defines a new BGP Path Attribute, referred
   to as D-PATH (Domain PATH), which provides loop prevention for
   gateway nodes by protecting against control plane loops.  The
   introduction of D-PATH modifies the BGP best path selection process
   for Multiprotocol BGP routes of SAFI 128 (IPVPN) and EVPN IP Prefix
   routes.  As a result, this specification updates the BGP best path
   selection procedure, but only in the context of IPVPN and EVPN route
   families.
