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 any combination of EVPN and IPVPN domains, it becomes
necessary to define the interworking mechanisms among these BGP
domains (EVPN and VPN-IP) to ensure seamless end-to-end tenant
connectivity. This document defines these interworking procedures.
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 inter-subnet forwarding routes of SAFI 128
(IPVPN) and SAFI 70 (EVPN). As a result, this specification updates
the BGP best path selection procedure, but only in the context of
IPVPN and EVPN route families.
