metric-style
To generate and accept old-style, new-style, or both styles of type, length, and values (TLV), congure a router.
Syntax
metric-style {narrow [transition] | transition | wide [transition]} [level-1 |
level-2]
To return to the default values, use the no metric-style {narrow [transition] | transition |
wide [transition]} [level-1 | level-2] command.
Parameters
narrow Allows you to generate and accept old-style TLVs. The metric range is from 0 to 63.
transition Allows you to generate both old-style and new-style TLVs. The metric range is from 0 to
63.
wide Allows you to generate and accept only new-style TLVs. The metric range is from 0 to
16777215.
level-1 Enables the metric style on Level 1.
level-2 Enables the metric style on Level 2.

Usage Information
If you enter the metric-style wide command, the system generates and accepts only new-style TLVs. The
router uses less memory and other resources rather than generating both old-style and new-style TLVs.
The new-style TLVs have wider metric elds than old-style TLVs.
Related Commands isis metric — congures a metric for an interface.
multi-topology
Enables multi-topology IS-IS. It also allows enabling/disabling of old and new style TLVs for IP prex information in the LSPs.
Syntax
multi-topology [transition]
To return to a single topology conguration, use the no multi-topology [transition] command.
