LISP Traffic Engineering Use-Cases
draft-ietf-lisp-te-06
Abstract
This document describes how LISP reencapsulating tunnels can be used
for Traffic Engineering purposes. The mechanisms described in this
document require no LISP protocol changes but do introduce a new
locator (RLOC) encoding. The Traffic Engineering features provided
by these LISP mechanisms can span intra-domain, inter-domain, or
combination of both.
Status of This Memo
