Example for Configuring IPv6 NFVI Distributed Gateway

This section provides an example for configuring IPv6 NFVI distributed gateway in a typical usage scenario.

Networking Requirements

Huawei's NFVI telecommunications (telco) cloud is a networking solution that incorporates Data Center Interconnect (DCI) and data center network (DCN) technologies. Mobile phone IPv6 traffic enters the DCN and accesses its virtualized unified gateway (vUGW) and virtual multiservice engine (vMSE). After being processed by these, the phone traffic is forwarded over the Internet through the DCN to the destination devices. Equally, response traffic sent over the Internet from the destination devices to the mobile phones also undergoes this process. For this to take place and to ensure that the traffic is balanced within the DCN, you need to deploy the NFVI distributed gateway function on the DCN.

Figure 1 Configuring IPv6 NFVI distributed gateway

Interfaces 1 through 5 in this example represent GE 0/1/1, GE 0/1/2, GE 0/1/3, GE 0/1/4, and GE 0/1/5, respectively.



Figure 1 shows the DCN on which the NFVI distributed gateway is deployed. DCGW1 and DCGW2 are the DCN's border gateways. The DCGWs exchange Internet routes with the external network. L2GW/L3GW1 and L2GW/L3GW2 access the virtualized network functions (VNFs). As virtualized NEs, VNF1 and VNF2 can be deployed separately to implement the functions of the vUGW and vMSE. VNF1 and VNF2 are connected to L2GW/L3GW1 and L2GW/L3GW2 through respective interface process units (IPUs).

This networking combines the distributed gateway function and the EVPN VXLAN active-active gateway function:

  • The EVPN VXLAN active-active gateway function is deployed on DCGW1 and DCGW2. Specifically, a bypass VXLAN tunnel is set up between DCGW1 and DCGW2. In addition, they use a virtual anycast VTEP address to establish VXLAN tunnels with L2GW/L3GW1 and L2GW/L3GW2.

  • The distributed gateway function is deployed on L2GW/L3GW1 and L2GW/L3GW2, and a VXLAN tunnel is established between them.

The NetEngine 8000 F can be deployed as a DCGW and L2GW/L3GW in this networking.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a routing protocol on each DCGW and each L2GW/L3GW to ensure Layer 3 communication. OSPF is used in this example.
  2. Configure an EVPN instance and bind it to a BD on each DCGW and each L2GW/L3GW.
  3. Configure an L3VPN instance and bind it to a VBDIF interface on each DCGW and each L2GW/L3GW.
  4. Configure BGP EVPN on each DCGW and each L2GW/L3GW.
  5. Configure a VXLAN tunnel on each DCGW and each L2GW/L3GW.
  6. On each L2GW/L3GW, configure a Layer 2 sub-interface that connects to a VNF and static VPN routes to the VNF.
  7. On each L2GW/L3GW, configure BGP EVPN to import static VPN routes, and configure a route policy for the L3VPN instance to keep the original next of the static VPN routes.
  8. On each DCGW, configure default static routes for the VPN instance and loopback routes used to establish a VPN BGP peer relationship with a VNF. Then configure a route policy for the L3VPN instance so that the DCGW can advertise only the default static routes and loopback routes through BGP EVPN.
  9. Configure each DCGW to establish a VPN BGP peer relationship with a VNF.
  10. Configure load balancing on each DCGW and each L2GW/L3GW.

Procedure

  1. Assign an IP address to each device interface, including the loopback interfaces.

    For configuration details, see Configuration Files in this section.

  2. Configure a routing protocol on each DCGW and each L2GW/L3GW to ensure Layer 3 communication. OSPF is used in this example.

    For configuration details, see Configuration Files in this section.

  3. Configure an EVPN instance and bind it to a BD on each DCGW and each L2GW/L3GW.

    Run the display bgp vpnv6 vpn-instance vpn1 routing-table command on each DCGW. The command output shows that the DCGW has received the mobile phone route (destined for 2001:DB8:10::10 in this example) from the VNF and the next hop of the route is the VNF IP address. The following example uses the command output on DCGW1:
