Configuring Metric Type
metric-style narrow
metric-style transition
metric-style wide
356
Extensions to IS-IS traffic engineering enable the use of bigger metrics. You can specify
whether your router accepts, generates, or accepts and generates only old-style metrics,
only new-style metrics, or both.
Use to specify that the router generates and accepts only old-style TLV tuples.
Old-style TLVs refers to TLVs having metrics with a narrow (six-bit) field with a value
in the range 0–63. New-style TLVs refers to TLVs having metrics with a wider field, as
provided for in current extensions to IS-IS traffic engineering.
Use the transition option to accept old-style and new-style metrics; only old-style
metrics are generated.
Specify whether the command applies to level 1, level 2, or both.
Example
host1(config-router)#metric-style narrow level-2
Use the no version to restore the default, which is to generate and accept only old-style
TLVs with narrow (six-bit) metric fields.
See metric-style narrow
Use to specify that the router generates and accepts both old-style and new-style TLV
tuples.
Old style refers to TLVs having metrics with a narrow (six-bit) field with a value in the
range 0–63. New style refers to TLVs having metrics with a wider field, as provided for
in current extensions to IS-IS traffic engineering.
Specify whether the command applies to level 1, level 2, or both.
Example
host1(config-router)#metric-style transition level-1
Issuing this command results in more resource usage than issuing the metric-style
narrow or metric-style wide commands.
Use the no version to restore the default, which is to generate and accept only old-style
TLVs with narrow (six-bit) metric fields.
See metric-style transition
Use to specify that the router generates and accepts only new-style TLV tuples.
Old style refers to TLVs having metrics with a narrow (six-bit) field with a value in the
range 0–63. New style refers to TLVs having metrics with a wider field, as provided for
in current extensions to IS-IS traffic engineering.
