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 elds than old-style TLVs.
When wide transition is congured, 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.
