Configuring MPLS Traffic Engineering for IS-IS
This task explains how to configure IS-IS for MPLS TE. This task is optional.
For a description of the MPLS TE tasks and commands that allow you to configure the router to support
tunnels, configure an MPLS tunnel that IS-IS can use, and troubleshoot MPLS TE, see Implementing MPLS
Traffic Engineering on Cisco ASR 9000 Series Aggregation Services Router MPLS Configuration Guide
Before You Begin
Your network must support the MPLS Cisco IOS XR software feature before you enable MPLS TE for IS-IS
on your router.
You must enter the commands in the following task list on every IS-IS router in the traffic-engineered
Note
portion of your network.
MPLS traffic engineering currently does not support routing and signaling of LSPs over unnumbered IP
Note
links. Therefore, do not configure the feature over those links.
