IS-IS uses a single, required, default metric with a maximum path value of 1023. The metric is arbitrary and a network administrator typically assigns it.
Any single link can have a maximum value of 63; path metrics are calculated by summing link values.
The old style metric is a 6 bits field. So it offers at most 64 different metrics (0 to 63). Moreover the aggregated metric (max cost) was limited to 1023.
