Context
MPLS TE supports strong traffic engineering capabilities and provides various QoS guarantees. Due to live network limitations, such as application types and costs, deploying MPLS TE on the entire network is difficult. Therefore, LDP over TE can be used to deploy MPLS TE on a core area and LDP on non-core areas.
Pre-configuration Tasks
Before configuring
LDP over TE, complete the following tasks:
Configure IGP to implement the reachability between LSRs.
Configure basic MPLS functions of all nodes and interfaces.
Enable MPLS LDP on the interface in the non-TE domain.
Configure RSVP-TE Tunnel on the TE node.
Configuration Procedure
Configure LDP over
TE according to the following sequence.
