Traffic engineering enables network operators to move traffic flows away from the shortest path selected by the IGP and onto a less congested physical path.
Traffic engineering can be used to balance the traffic load on the various links, routers, and switches in the network so that none are overutilized or underutilized. Traffic engineering using MPLS should be thought of as assistance to the routing infrastructure that provides additional information used in forwarding traffic along alternate paths.
Use the commands in this chapter to:
- Enable/disable traffic engineering
- Configure paths for traffic flow
- Configure constraint-based routing in which the path meets resource requirements such as bandwidth requirements and priority versus other flows
- Create, delete and modify tunnels
- Display traffic engineering data for a specific tunnel or interface, or for the system as a whole
