The ipv6 filter-policy import command configures IS-IS to filter received IPv6 routes so that only given routes are added to the IPv6 routing table.
The undo ipv6 filter-policy import command removes the configuration.
By default, IS-IS does not filter received IPv6 routes.
ipv6 filter-policy { acl6-number | acl6-name acl6-name-string | ipv6-prefix ipv6-prefix-name | route-policy route-policy-name | route-filter route-filter-name } import
undo ipv6 filter-policy [ acl6-number | acl6-name acl6-name-string | ipv6-prefix ipv6-prefix-name | route-policy route-policy-name | route-filter route-filter-name ] import
| 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-string |
Specifies the name of a named basic ACL6. |
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). |
| 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, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| route-policy route-policy-name |
Specifies the name of a route-policy to filter routes based on tags and other protocol parameters. |
The name is a string of 1 to 200 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| route-filter route-filter-name |
Specifies the name of a filter policy to filter routes based on tags and other protocol parameters. |
The value is a string of 1 to 200 case-sensitive characters, spaces not supported. If parameters are included in the referenced route-filter, specify values for them in the format of (var1, var2, ...var8) behind the route-filter name. A maximum of eight parameters can be specified, and each value ranges from 1 to 200 characters. |
Usage Scenario
To configure IS-IS to filter received IPv6 routes so that only given routes are added to the IPv6 routing table, run the ipv6 filter-policy import command. The ipv6 filter-policy import command takes effect only after IPv6 is enabled for the IS-IS process. For details, see isis ipv6 enable.
