no redistribute isis {level-1 | level-2} into {level-2 | level-1}
Parameters
level-1 Specifies to redistribute level 1 routes into either level 1 or level 2 IS-IS
routes.
level-2 Specifies to redistribute level 2 routes into either level 1 or level 2 IS-IS
routes.
into
Specifies to redistribute the preceding IS-IS level routes into the
following IS-IS level routes.
level-2 Specifies to redistribute either level 1 or level 2 routes into level 1 IS-IS
routes.
level-1 Specifies to redistribute either level 1 or level 2 routes into level 2 IS-IS
routes.
distribute-list LIST-NAME (Optional) Specifies the distribute list that controls the IS-IS
redistribution.
Default
By default, no redistribution is configured.
Command Mode
Router Configuration Mode.
Address Family Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
In IS-IS, all areas are stub areas, which means that no routing information is leaked from the backbone
(Level 2) into areas (Level 1). Level 1-only routers use default routing to the closest Level 1-2 router in
their area. This redistribution enables Level 1-only routers to pick the best path for an IP prefix to get out
of the area. This is an IP-only feature, CLNS routing is still stub routing. For more control and scalability, a
distribute list can control which Level 2 IP routes can be redistributed into Level 1.
Example
This example shows how to redistribute level 1 into level 2 with access list “list1”.
Switch# configure terminal
Switch(config)# router isis
Switch(config-router)# redistribute isis level-1 into level-2 distribute-list list1
Switch(config-router)#
48-33 router isis
This command is used to enable the IS-IS routing protocol and to specify an IS-IS process. Use the no
command to disable IS-IS routing.
