Lou Berger, R. White, Eric Rosen · 2009
The BGP Encapsulation Subsequence Address Family Identifiers (SAFI) provides a method for the dynamic exchange of encapsulation information, and the indication of encapsulation protocol types to be used for different next hops. Currently support for GRE, L2TPv3 and IP in IP tunnel types are defined. This document defines support for IPsec tunnel types.
