Information
To redistribute a default route (0.0.0.0/0), configure the default-information originate command.
Changing or disabling a keyword in this command will not affect the state of the other command
keywords.
When an LSP with an internal metric is received, the FTOS considers the route cost taking into
consideration the advertised cost to reach the destination.
Redistributed routing information is filtered with the distribute-list out command to ensure that the
routes are properly are passed to the receiving routing protocol.
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.
