Version 6.3.1.0 Introduced.
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 advertises depends on the metric-style
command configuration. If the metric-style command 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 the LSPs is 63. If the
metric-style command
is set for Wide mode, the metric value in the default-information originate
command is advertised.
