How a metric value assigned to a redistributed route is advertised depends on how on
the configuration of the metric-style command. If the metric-style command is
set for Narrow or Transition mode and the metric value in the redistribute
command is set to a number higher than 63, the metric value advertised in LSPs is 63. If
the metric-style command is set for Wide mode, the metric value in the
redistribute command is advertised.
