level-1 (OPTIONAL) Routes are independently redistributed into IS-IS as Level 1 routes.
level-1-2 (OPTIONAL) Routes are independently redistributed into IS-IS as Level-1-2 routes.
level-2 (OPTIONAL) Routes are independently redistributed into IS-IS as Level 2 routes.
This setting is the default.
route-map map-
name
(OPTIONAL) If you do not enter the route-map argument, all routes are
redistributed. If a map-name value is not specified, no routers are imported.

● metric metric-value = 0
● metric-type= internal; level-2
Command Modes
● ROUTER ISIS (for IPv4)

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), configure the default-information originate
command.
Changing or disabling a keyword in this command does not affect 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 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 is 63. If the metric-style command is set for Wide mode, the metric value in the
redistribute command is advertised.

Commands
● default-information originate — generates a default route for the IS-IS domain.
● distribute-list out — suppresses networks from being advertised in updates. This command filters
redistributed routing information.
redistribute bgp
Redistribute routing information from a BGP process. (New command in Release 6.3.1.)
Syntax
redistribute bgp AS number [level-1| level-1-2 | level-2] [metric metric-
value] [metric-type {external| internal}] [route-map map-name]
To return to the default values, use the no redistribute bgp command with the appropriate
parameters.
Parameters
AS number Enter a number that corresponds to the autonomous system number. The range is
from 1 to 65355.
level-1 (OPTIONAL) Routes are independently redistributed into IS-IS Level 1 routes only.
level-1-2 (OPTIONAL) Routes are independently redistributed into IS-IS Level 1 and Level 2
routes.
level-2 (OPTIONAL) Routes are independently redistributed into IS-IS as Level 2 routes
only. This setting is the default.
