Internet Engineering Task Force (IETF) L. Jakab Request for Comments: 7215 Cisco Systems Category: Experimental A. Cabellos-Aparicio ISSN: 2070-1721 F. Coras J. Domingo-Pascual Technical University of Catalonia D. Lewis Cisco Systems April 2014 Locator/Identifier Separation Protocol (LISP) Network Element Deployment Considerations Abstract This document is a snapshot of different Locator/Identifier Separation Protocol (LISP) deployment scenarios. It discusses the placement of new network elements introduced by the protocol, representing the thinking of the LISP working group as of Summer 2013. LISP deployment scenarios may have evolved since then. This memo represents one stable point in that evolution of understanding. Status of This Memo This document is not an Internet Standards Track specification; it is published for examination, experimental implementation, and evaluation. This document defines an Experimental Protocol for the Internet community. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Not all documents approved by the IESG are a candidate for any level of Internet Standard; see Section 2 of RFC 5741.
