MPLS

MPLS Common Configurations: Multiprotocol Label Switching (MPLS) configurations for the forwarding plane involve the MPLS time to live (TTL) handling modes, penultimate hop popping (PHP), and MPLS maximum transmission unit (MTU).

MPLS TE Configuration: This chapter describes the principles for Multiprotocol Label Switching Traffic Engineering (MPLS TE), Resource Reservation Protocol (RSVP) TE tunnels, RSVP signaling parameter adjustment, RSVP authentication, tunnel parameter adjustment, measures for adjusting TE forwarding, the bandwidth flood threshold, tunnel re-optimization, MPLS TE fast reroute (FRR), MPLS TE Auto FRR, constraints-routed label switched path (CR-LSP) backup, isolated LSP computation, RSVP graceful restart (GR), static bidirectional forwarding detection (BFD) for CR-LSP, dynamic BFD for CR-LSP, MPLS TE distribution, and how to configure MPLS TE, and provides configuration examples.

MPLS LDP Configuration: The Multiprotocol Label Switching (MPLS) Label Distribution Protocol (LDP) defines the messages in and procedures for distributing labels. MPLS LDP is used by label switching routers (LSRs) to negotiate session parameters, distribute labels, and then establish label switched paths (LSPs).

Seamless MPLS Configuration: This section describes how to configure seamless Multiprotocol Label Switching (MPLS) in various usage scenarios.

GMPLS UNI Configuration: This document describes basic principles of Generalized Multiprotocol Label Switching User-to-Network Interface (GMPLS UNI), configuration procedures, and configuration examples of GMPLS UNI bidirectional tunnels based on Resource Reservation Protocol-Technical Engineering (RSVP-TE).
