Configuring IS-IS route redistribution

Perform this task to redistribute routes from other routing protocols into IS-IS. You can specify a cost for redistributed routes and specify the maximum number of redistributed routes.

To configure IS-IS route redistribution from other routing protocols:

Step

Command

Remarks

1. Enter system view.

system-view

N/A

2. Enter IS-IS view.

isis [ process-id ] [ vpn-instance vpn-instance-name ]

N/A

3. Redistribute routes from other routing protocols or other IS-IS processes.

import-route protocol [ process-id | all-processes | allow-ibgp ] [ cost cost | cost-type { external | internal } | [ level-1 | level-1-2 | level-2 ] | route-policy route-policy-name | tag tag ] *

By default, no route is redistributed.

By default, if no level is specified, this command redistributes routes into the Level-2 routing table.

This command redistributes only active routes. To display active routes, use the display ip routing-table protocol command.

4. (Optional.) Configure the maximum number of redistributed Level 1/Level 2 IPv4 routes.

import-route limit number

By default, the maximum number of redistributed Level 1/Level 2 IPv4 routes is not configured.
