Usage Information
If you enter the metric-style wide command, the Dell Networking OS 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 fields than old-style TLVs.
When wide transition is configured, narrow metric is sent for the narrow metric TLV and the actual wide metric is
sent in wide metric TLV. The receiver can choose to use the metric that is requires.
