The isis ipv6 tag-value command configures an IPv6 administrative tag for an interface.
The undo ipv6 isis tag-value command deletes the IPv6 administrative tag of an interface.
By default, an interface does not have an IPv6 administrative tag.
isis ipv6 tag-value tag [ level-1 | level-2 ]
undo isis ipv6 tag-value [ tag ] [ level-1 | level-2 ]
| Parameter | Description | Value |
|---|---|---|
| tag | Specifies the administrative tag. | The value is an integer ranging from 1 to 4294967295. |
| level-1 | Specifies the administrative tag of a Level-1 interface. | - |
| level-2 | Specifies the administrative tag of a Level-2 interface. | - |

If the IS-IS cost style is wide, wide-compatible, or compatible, the administrative tag for an interface is advertised using an LSP.
If no level is specified, an administrative tag is configured for both Level-1 and Level-2 interfaces.
If no topology instance name is specified, an IPv6 base topology is configured by default.
To make the isis ipv6 tag-value command take effect, do as follows first:
Enable IPv6 globally in the system view by using the ipv6 command.
Enable an IS-IS process by using the isis command.
Enable IPv6 capability of the IS-IS process by using the ipv6 enable command in the IS-IS view.
On each interface that runs an IS-IS process, enable IPv6 capability by using the ipv6 enable command.
Enable IS-IS on each interface by using the isis ipv6 enable command.
