Binding Interfaces to a VPN Instance

Binding Interfaces to a VPN Instance

After an interface is bound to a VPN instance, the interface becomes a part of the VPN. Packets entering the interface will be forwarded based on the VRF table of the VPN.


After a VPN instance is configured on a PE, an interface that belongs to the VPN must be bound to the VPN instance. Otherwise, the interface functions as a public network interface and cannot forward VPN data.

Perform the following steps on each PE that connects to CEs.


  1. Run system-view

    The system view is displayed.

  2. Run interface interface-type interface-number

    The interface view is displayed.

  3. Run ip binding vpn-instance vpn-instance-name

    The interface is bound to the VPN instance.


    Using the ip binding vpn-instance command will delete Layer 3 (including IPv4 and IPv6) configurations, such as the IP address and routing protocol, on the interface. Reconfigure them after using the ip binding vpn-instance command if needed.

  4. Run ip address ip-address { mask | mask-length }

    An IP address is configured for the interface.

    Some Layer 3 features, such as route exchange between the PE and CE, can be configured only after an IP address is configured for the VPN interface on the PE.

  5. Run commit

    The configuration is committed.
