Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
To redistribute a default route (0.0.0.0/0), congure the default-information originate command.
Changing or disabling a keyword in this command does not aect the state of the other command keywords.
When an LSP with an internal metric is received, the system considers the route cost while considering the
advertised cost to reach the destination.
Redistributed routing information is ltered 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 conguration 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.
