Abstract

Historically MPLS label distribution was driven by protocols like LDP, RSVP and LBGP. All of those protocols are session oriented. In order to obtain a label binding for a given destination FEC from a given router one needs first to establish an LDP/RSVP/LBGP session with that router. Advertising MPLS labels in IGPs [I-D.gredler-rtgwg-igp-label-advertisement] describes several use cases where utilizing the flooding machinery of link-state protocols for MPLS label distribution allows to obtain the binding without requiring to establish an LDP/RSVP/LBGP session with that router. This document describes the protocol extension to distribute MPLS label bindings using the IS-IS protocol.
