Configuring received/redistributed route filtering
Perform this task to filter received and redistributed routes by using an IP prefix list. You can also configure RIP to receive routes only from a specified neighbor.
To configure route filtering:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter RIP view. | rip [ process-id ] [ vpn-instance vpn-instance-name ] | N/A |
3. Configure the filtering of received routes. | filter-policy { acl-number | gateway prefix-list-name | prefix-list prefix-list-name [ gateway prefix-list-name ] } import [ interface-type interface-number ] | By default, the filtering of received routes is not configured. This command filters received routes. Filtered routes are not installed into the routing table or advertised to neighbors. |
4. Configure the filtering of redistributed routes. | filter-policy { acl-number | prefix-list prefix-list-name } export [ protocol [ process-id ] | interface-type interface-number ] | By default, the filtering of redistributed routes is not configured. This command filters redistributed routes, including routes redistributed with the import-route command. |
