Abstract

Multiprotocol Label Switching (MPLS) signaling is documented in 'RSVP-TE: Extensions to RSVP for LSP Tunnels', RFC 3209, using mechanisms inherited from 'Resource ReserVation Protocol -- Version 1 Functional Specification', RFC 2205. MPLS includes the concept of pre-emption where, for administrative reasons such as contention for system resources, a new Label Switched Path (LSP) may displace an existing LSP. This document clarifies the procedures for MPLS pre-emption in the light of implementation experience. The procedures in this document update those described in RFC 2205 and RFC 3209, but apply only to RSVP-TE used in the MPLS context.
