How To Implement Traffic Engineering; Building Mpls-Te Topology - Cisco ASR 9000 Series Configuration Manual

Implementing MPLS Traffic Engineering

How to Implement Traffic Engineering

Traffic engineering requires coordination among several global neighbor routers, creating traffic engineering
tunnels, setting up forwarding across traffic engineering tunnels, setting up FRR, and creating differential
service.
These procedures are used to implement MPLS-TE:

Building MPLS-TE Topology

Perform this task to configure MPLS-TE topology (required for traffic engineering tunnel operations).
Before You Begin
Before you start to build the MPLS-TE topology, you must have enabled:
• IGP such as OSPF or IS-IS for MPLS-TE.
• MPLS Label Distribution Protocol (LDP).
• RSVP on the port interface.
• Stable router ID is required at either end of the link to ensure that the link is successful. If you do not
• If you are going to use nondefault holdtime or intervals, you must decide the values to which they are

which can result in an unstable link.
