The ipv4-labeled-unicast vpn-instance command enables a BGP-labeled-VPN instance IPv4 address family and displays the BGP-labeled-VPN instance IPv4 address family view.
The undo ipv4-labeled-unicast vpn-instance command deletes all the configurations in the BGP-labeled-VPN instance IPv4 address family view.
By default, the BGP-IPv4 unicast address family view is displayed.
| Parameter | Description | Value |
|---|---|---|
| vpn-instance-name |
Specifies the name of a VPN instance with which a BGP-labeled-VPN instance IPv4 address family is associated. |
The value is a string of 1 to 31 case-sensitive characters, spaces not supported. In addition, the VPN instance name must not be _public_. When double quotation marks are used around the string, spaces are allowed in the string. |
Usage Scenario
Before you perform configurations in a BGP-labeled-VPN instance IPv4 address family, run the ipv4-labeled-unicast vpn-instance command in the BGP view to enable it. After the configuration, the BGP-labeled-VPN instance IPv4 address family view is displayed. By default, BGP uses the BGP-IPv4 unicast address family.
Precautions
If the local device is enabled to exchange BGP labeled routes with a specified peer or peer group using the peer enable command in both the BGP-labeled-VPN instance IPv4 address family view and BGP-VPN instance IPv4 address family view, but the peer or peer group is enabled to send or receive BGP labeled routes using a route-policy and the peer label-route-capability command only in the BGP-IPv4 unicast address family view, routes may be withdrawn or overwritten unexpectedly.
