IP Prefix Advertisement in Ethernet VPN
RFC 9136, “IP Prefix Advertisement in Ethernet VPN”, is a Proposed Standard document published in October 2021 by J. Rabadan, W. Henderickx, J. Drake, W. Lin, A. Sajassi. The canonical text is published by the RFC Editor.
Abstract
The BGP MPLS-based Ethernet VPN (EVPN) (RFC 7432) mechanism provides a flexible control plane that allows intra-subnet connectivity in an MPLS and/or Network Virtualization Overlay (NVO) (RFC 7365) network. In some networks, there is also a need for dynamic and efficient inter-subnet connectivity across Tenant Systems and end devices that can be physical or virtual and do not necessarily participate in dynamic routing protocols. This document defines a new EVPN route type for the advertisement of IP prefixes and explains some use-case examples where this new route type is used.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
