LISP Canonical Address Format (LCAF)
Abstract
This document defines a canonical address format encoding used in
Locator/ID Separation Protocol (LISP) control messages and in the
encoding of lookup keys for the LISP Mapping Database System.
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 7841.
