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 IPv4 unicast address family view. | isis [ process-id ] [ vpn-instance vpn-instance-name ] cost-style { wide | wide-compatible } address-family ipv4 [ unicast ] | N/A |
3. Redistribute routes from other routing protocols or other IS-IS processes. | import-route protocol [ as-number ] [ process-id | all-processes | allow-ibgp ] [ allow-direct | cost cost-value | 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. |
