Configuring OSPFv3 route redistribution
Because OSPFv3 is a link state routing protocol, it cannot directly filter LSAs to be advertised. OSPFv3 filters only redistributed routes. Only routes that are not filtered out can be advertised in LSAs.
Executing the import-route or default-route-advertise command on a router makes it become an ASBR.
To configure OSPFv3 route redistribution:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter OSPFv3 view. | ospfv3 [ process-id | vpn-instance vpn-instance-name ] * | N/A |
3. (Optional.) Specify a default cost for redistributed routes. | default cost value | The default setting is 1. |
4. Configure OSPFv3 to redistribute routes from other routing protocols. | import-route protocol [ process-id | all-processes | allow-ibgp ] [ cost cost | route-policy route-policy-name | type type ] * | By default, route redistribution is disabled. |
5. (Optional.) Configure OSPFv3 to redistribute a default route. | default-route-advertise [ [ always | permit-calculate-other ] | cost cost | route-policy route-policy-name | type type ] * | By default, no default route is redistributed. This command can only inject and advertise a default route. |
6. (Optional.) Configure OSPFv3 to filter redistributed routes. | filter-policy { acl6-number | prefix-list prefix-list-name } export [ protocol [ process-id ] ] | By default, OSPFv3 accepts all redistributed routes. This command filters only routes redistributed with the import-route command. If the import-route command is not configured, executing this command does not take effect. |
