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 will be 63. If the metric-style command is set for wide mode, an the metric value in the
redistribute command is advertised.

route-map map-name map-name is an identifier for a configured route map.

to the current routing protocol.
If you do not specify a

specify a keyword, but fail to list route map tags, no routes will be imported.
