Usage Guidelines

Usage Scenario

When you deploy MPLS TE on the MPLS backbone network where IS-IS is used to advertise routes, run this command to enable TE features on a specified level for an IS-IS process.

Prerequisites

The cost-style command has been executed to set the cost type of IS-IS packets to wide, compatible, or wide-compatible.

Precautions

The IS-IS level in this command must be the same as that on the MPLS backbone network.

Example

# Enable TE on level-2 for IS-IS process 1.

<HUAWEI> system-view
[HUAWEI] isis 1
[HUAWEI-isis-1] cost-style compatible
[HUAWEI-isis-1] traffic-eng level-2
