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.
