Parameters
level-1: Enables MPLS TE for IS-IS at Level-1.
level-2: Enables MPLS TE for IS-IS at Level-2.
Usage guidelines
If you do not specify an IS-IS level, this command enables MPLS TE for IS-IS at both Level-1 and Level-2.
IS-IS TE uses a sub-TLV of the extended IS reachability TLV (type 22) to carry TE attributes. Because the
extended IS reachability TLV carries wide metrics, specify a wide metric-compatible metric style for the
IS-IS process before enabling IS-IS TE. Available metric styles for IS-IS TE include wide, compatible, or
wide-compatible. For more information about IS-IS, see Layer 3—IP Routing Configuration Guide.
If you execute this command multiple times, the most recent configuration takes effect. For example, if you
first execute the mpls te enable command and then the mpls te enable level-1 command, MPLS TE is
enabled for Level-1 and disabled for Level-2.
After you enable MPLS TE for both Level-1 and Level-2 by using the mpls te enable command, executing
the undo mpls te enable level-1 command disables MPLS TE for Level-1, and MPLS TE is still enabled for
Level-2. Similarly, the undo mpls te enable level-2 command only disables MPLS TE for Level-2.
Examples
# Enable MPLS TE for IS-IS process 1 at Level-2.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] cost-style compatible
[Sysname-isis-1] mpls te enable level-2
