The ipv4-family vpn-instance command enables the BGP-VPN instance address family and displays the address family view.
The undo ipv4-family vpn-instance command deletes the configurations in the BGP-VPN instance address family.
By default, the BGP-IPv4 unicast address family view is displayed.
| Parameter | Description | Value |
|---|---|---|
| vpn-instance-name |
Associates a specified VPN instance with the BGP-IPv4 address family. You can enter the BGP-VPN instance address family view using the parameter. |
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 performing BGP configurations in a BGP-VPN instance address family, you need to run the ipv4-family vpn-instance command in the BGP view to enable the BGP-VPN instance address family and enter the address family view. By default, BGP uses the IPv4 unicast address family.
Precautions
If you attempt to configure the IPv4 VPN address family view in the BGP multi-instance view and MVPN services have been configured for the VPN instance, the configuration fails.
