The filter-policy export command configures a global, protocol, or interface export policy so that only the routes that match the export policy can be added to the routing table and advertised through update packets.
The undo filter-policy export command disables route filtering.
The filter-policy import command filters the routes that are received in RIP update packets.
The undo filter-policy import command disables route filtering.
By default, no export policy is configured.

| Parameter | Description | Value |
|---|---|---|
| acl-name acl-name |
Specifies the name of a named basic ACL. |
The value is a string of 1 to 64 case-sensitive characters without spaces. The value must start with a letter (a to z or A to Z, case sensitive). |
| acl-number |
Specifies the number of a basic ACL that is used to filter routes based on the destination address. |
The value is an integer and ranges from 2000 to 2999. |
| ip-prefix ip-prefix-name |
Specifies the name of an IP prefix list that is used to filter routes based on the destination address. |
The name is a string of 1 to 169 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| static |
Filters static routes. |
- |
| direct |
Filters direct routes. |
- |
| bgp |
Filters BGP routes. |
- |
| rip |
Filters RIP routes. |
- |
| ospf |
Filters OSPF routes. |
- |
| isis |
Filters IS-IS routes. |
- |
| process-id |
Specifies the process ID. process-id is required when the protocol is RIP, OSPF, or IS-IS. |
The value is an integer ranging from 1 to 4294967295. |
| interface-type |
Specifies the interface type. |
- |
| interface-number |
Specifies the interface number. |
- |
| gateway ip-prefix-name |
Filters routes based on the distributing gateway. |
The value is case-sensitive. |
Usage Scenario
If you want to delete an interface-based export policy, specify interface-type interface-number. Export policies can be deleted from only one interface each time. The command is configured in the RIP process. If you want to filter routes based on an interface or a protocol, you can configure only one export policy for the interface or protocol. If no interface or protocol is specified, the configured export policy takes effect globally. You can configure only one export policy each time.
Configuration Impact
If the command is run more than once, the latest configuration overrides the previous one.
