Usage
Information
When you use this command to redistribute routes into a routing domain, the router becomes an
autonomous system (AS) boundary router. An AS boundary router does not always generate a default
route into a routing domain. The router still requires its own default route before it can generate one.
How a metric value assigned to a default route is advertised depends on how on the configuration of
the metric-style command. If the metric-style is set for narrow mode and the metric value in the
default-information originate command is set to a number higher than 63, the metric value advertised
in LSPs will be 63. If the metric-style is set for wide mode, their the metric value in the
default-information originate command is advertised.
