Configuring the TLV Metric Style

By default the IS-IS metric style defaults to both wide and narrow. The narrow metric is a 6-bit metric as defined in ISO 10589. The wide metric is a 4-byte metric and configures a intermediate system to generate and accept type, length, and value (TLV) object 135 for IP addresses. The TLV metric style can be configured for either both wide and narrow or wide.

Use the metric-style command in IS-IS configuration mode to configure the TLV metric style for the IS-IS intermediate system.
