filter-policy export (RIPng)
Function
The filter-policy export command specifies the filtering policy for sent routes.
The undo filter-policy export command cancels the configuration.
By default, no filtering policy is configured.
Format
filter-policy { acl6-number | acl6-name acl6-name | ipv6-prefix ipv6-prefix-name | route-policy route-policy-name } export [ protocol [ process-id ] ]
undo filter-policy [ acl6-number | acl6-name acl6-name | ipv6-prefix ipv6-prefix-name | route-policy route-policy-name ] export [ protocol [ process-id ] ]
Parameters
| Parameter | Description | Value |
|---|---|---|
| acl6-number | Specifies the number of a basic IPv6 ACL. | The value is an integer ranging from 2000 to 2999. |
| acl6-name acl6-name | Specifies the name of a named IPv6 ACL, which is case sensitive. | The name is a string of 1 to 32 case-sensitive characters without spaces. |
| ipv6-prefix ipv6-prefix-name | Specifies the name of an IPv6 prefix list. | The name is a string of 1 to 169 case-sensitive characters without spaces. |
| route-policy route-policy-name | Specifies the name of the routing policy. | The name is a string of 1 to 40 case-sensitive characters without spaces. |
| protocol | Specifies the name of a routing protocol from which routes are imported. | The value can be bgp, direct, isis, unr, ripng, static, or ospfv3. |
| process-id | Specifies the process ID of IS-IS, RIPng, or OSPFv3. | The value is an integer that ranges from 1 to 65535. |
Usage Guidelines
In some cases, you need to precisely control the advertisement of RIPng routes to meet complicated network requirements. RIPng can use an ACL or IPv6 prefix list to filter imported routes, allowing only the routes matching the IPv6 prefix list to be advertised to RIPng neighbors.
For a IPv6 ACL, when the rule command is used to configure a filtering rule, the filtering rule is effective only with the source address range that is specified by the source parameter and with the time period that is specified by the time-range parameter.
