MPLS Transport Profile Commands

This module describes the commands used to configure Transport Profile (MPLS-TP) in a Multiprotocol Label Switching (MPLS) network.

MPLS Transport Profile supported by IETF enables the migration of transport networks to a packet-based network that efficiently scale to support packet services in a simple and cost effective way. MPLS transport profile enables you to create tunnels that provide the transport network service layer over which IP and MPLS traffic traverse.

For detailed information about MPLS concepts, configuration tasks, and examples, see Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide.
