Abstract

   The applications of EVPN-based solutions ([RFC7432] and [RFC8365])
   have become pervasive in Data Center, Service Provider, and
   Enterprise segments. It is being used for fabric overlays and inter-
   site connectivity in the Data Center market segment, for Layer-2,
   Layer-3, and IRB VPN services in the Service Provider market segment,
   and for fabric overlay and WAN connectivity in Enterprise networks.
   For Data Center and Enterprise applications, there is a need to
   provide inter-site and WAN connectivity over public Internet in a
   secured manner with same level of privacy, integrity, and
   authentication for tenant's traffic as IPsec tunneling using IKEv2.
   This document presents a solution where BGP point-to-multipoint
   signaling is leveraged for key and policy exchange among PE devices
   to create private pair-wise IPsec Security Associations without IKEv2
   point-to-point signaling or any other direct peer-to-peer session
   establishment messages.
