Creating an L3VPN Instance and Binding It to a VBDIF Interface

Procedure

1. Run system-view

   The system view is displayed.

2. Create an L3VPN instance on each device.

   For IPv4 services, configure an IPv4 L3VPN instance.

   1. Run ip vpn-instance vpn-instance-name

      A VPN instance is created, and its view is displayed.

   2. Run ipv4-family

      The VPN instance IPv4 address family is created, and its view is displayed.

   3. Run route-distinguisher route-distinguisher

      An RD is set for the VPN instance IPv4 address family.

   4. Run vpn-target vpn-target &<1-8> [ both | export-extcommunity | import-extcommunity ] evpn

      One or multiple VPN targets are set for the VPN instance IPv4 address family.

   5. Run evpn mpls routing-enable

      The device is enabled to generate and advertise EVPN IP prefix routes and IRB routes.

   6. (Optional) Run tnl-policy policy-name evpn

      A specified tunnel policy is applied to the VPN instance IPv4 address family to associate the tunnel policy with the EVPN routes leaked to the VPN instance IPv4 address family.

   7. (Optional) Run import route-policy policy-name evpn

      An import route-policy is applied to the VPN instance IPv4 address family to filter EVPN routes to be imported to the VPN instance IPv4 address family. Perform this step to apply an import route-policy to the VPN instance IPv4 address family and set attributes for eligible EVPN routes. This enables the device to more precisely control EVPN routes to be imported into the VPN instance IPv4 address family more precisely.

   8. (Optional) Run export route-policy policy-name evpn

      An export route-policy is applied to the VPN instance IPv4 address family to filter EVPN routes to be advertised. Perform this step to apply an export route-policy to the VPN instance IPv4 address family and set attributes for eligible EVPN routes. This enables the device to more precisely control EVPN routes to be advertised.

   9. Run quit

      Exit the VPN instance IPv4 address family view.

   10. Run quit

       Exit the VPN instance view.

   For IPv6 services, configure an IPv6 L3VPN instance.

   1. Run ip vpn-instance vpn-instance-name

      A VPN instance is created, and its view is displayed.

   2. Run ipv6-family

      The VPN instance IPv6 address family is created, and its view is displayed.

   3. Run route-distinguisher route-distinguisher

      An RD is set for the VPN instance IPv6 address family.

   4. Run vpn-target vpn-target &<1-8> [ both | export-extcommunity | import-extcommunity ] evpn

      One or multiple VPN targets are set for the VPN instance IPv6 address family.

   5. Run evpn mpls routing-enable

      The device is enabled to generate and advertise EVPN IP prefix routes and IRB routes.

   6. (Optional) Run tnl-policy policy-name evpn

      A specified tunnel policy is applied to the VPN instance IPv6 address family to associate the tunnel policy with the EVPN routes leaked to the VPN instance IPv6 address family.

   7. (Optional) Run import route-policy policy-name evpn

      An import route-policy is applied to the VPN instance IPv6 address family to filter EVPN routes to be imported to the VPN instance IPv6 address family. Perform this step to apply an import route-policy to the VPN instance IPv6 address family and set attributes for eligible EVPN routes. This enables the device to more precisely control EVPN routes to be imported into the VPN instance IPv6 address family.

   8. (Optional) Run export route-policy policy-name evpn

      An export route-policy is applied to the VPN instance IPv6 address family to filter EVPN routes to be advertised. Perform this step to apply an export route-policy to the VPN instance IPv6 address family and set attributes for eligible EVPN routes. This enables the device to more precisely control EVPN routes to be advertised.

   9. Run quit

      Exit the VPN instance IPv6 address family view.

   10. Run quit

       Exit the VPN instance view.

3. Run interface vbdif bd-id

   A VBDIF interface is created, and the VBDIF interface view is displayed.

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

   The VBDIF interface is bound to a VPN instance.

5. (Optional) Run ipv6 enable

   IPv6 is enabled on the interface.

6. Run ip address ip-address { mask | mask-length } [ sub ] or ipv6 address { ipv6-address prefix-length | ipv6-address/prefix-length }

   An IPv4/v6 address is set for the VBDIF interface to implement Layer 3 communication.

7. (Optional) Run mac-address mac-address

   A MAC address is configured for the VBDIF interface.

8. Run arp collect host enable or ipv6 nd collect host enable

   The device is enabled to advertise host ARP/ND routes and IRB/IRBv6 routes.

9. Run commit

   The configuration is committed.
