BGP IPsec Tunnel Encapsulation Attribute
RFC 5566, “BGP IPsec Tunnel Encapsulation Attribute”, is a Proposed Standard document published in June 2009 by L. Berger, R. White, E. Rosen. It has been obsoleted by RFC 9012 — refer to the newer document for the authoritative version. The canonical text is published by the RFC Editor.
Abstract
The BGP Encapsulation Subsequent Address Family Identifier (SAFI) provides a method for the dynamic exchange of encapsulation information and for the indication of encapsulation protocol types to be used for different next hops. Currently, support for Generic Routing Encapsulation (GRE), Layer 2 Tunneling Protocol (L2TPv3), and IP in IP tunnel types are defined. This document defines support for IPsec tunnel types. [STANDARDS-TRACK]
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.
