Example for configuring VXLAN for a Virtual Network in Centralized Gateway Mode (BGP EVPN Mode)

Networking Requirements

An enterprise has constructed a mature campus network but does not have a dedicated data center network. All the servers of the enterprise are scattered in different departments and do not support centralized placement. The enterprise wants to construct a virtual data center network over the existing campus network to meet the following requirements:
  • Servers scattered in different departments form a virtual network, realizing resource integration and flexible service deployment.
  • A lot of VMs are deployed on servers. VMs in the same network segment achieve Layer 2 interconnection while VMs in different network segments achieve Layer 3 interconnection.
As shown in Figure 1, enterprise servers are deployed at different positions. Server1 and Server3 are in one network segment while Server2 and Server4 are in another network segment. Virtual extensible LAN (VXLAN) tunnels need to be used for Layer 2 interconnection between servers in the same network segment and for Layer 3 interconnection between servers in different network segments.
Figure 1 Configuring VXLAN for a virtual network in centralized gateway mode (BGP EVPN)

This example uses the S6730-S, S6730S-S, S5732-H, S5731-S, S5731S-S, S5731S-H, S6730-H, S6730S-H, S5731-H, S5720-HI, S5730-HI, or S6720-HI as an example to describe the configuration.

Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a routing protocol on VTEP1, VTEP2, and VTEP3 to ensure Layer 3 interconnection.
  2. Configure a deployment mode for the VXLAN access service on VTEP2 and VTEP3, and configure a VLAN on Switch1 and Switch2.
  3. Configure an EVPN instance on VTEP1, VTEP2, and VTEP3, and bind the instance to a bridge domain (BD).
  4. Configure a BGP EVPN peer relationship among VTEP1, VTEP2, and VTEP3.
  5. Configure the destination address of the VXLAN tunnel on VTEP1, VTEP2, and VTEP3.
  6. Configure a Layer 3 VXLAN gateway on VTEP1.

Layer 3 interconnection of the campus network is the basis of the virtual network. If Layer 3 interconnection has been implemented on the existing campus network, ignore step 1.

Procedure

  1. Configure a routing protocol.

    # Configure IP addresses of interfaces on VTEP2. The configurations of VTEP1 and VTEP3 are similar to the configurations of VTEP2, and are not mentioned here. When OSPF is used, the loopback interface addresses of devices must be advertised.

    <HUAWEI> system-view
[HUAWEI] sysname VTEP2
[VTEP2] interface loopback 1
[VTEP2-LoopBack1] ip address 10.2.2.2 32
[VTEP2-LoopBack1] quit
[VTEP2] interface gigabitethernet 0/0/1
[VTEP2-GigabitEthernet0/0/1] undo portswitch
[VTEP2-GigabitEthernet0/0/1] ip address 192.168.1.1 24
[VTEP2-GigabitEthernet0/0/1] quit
[VTEP2] ospf router-id 10.2.2.2

[VTEP2-ospf-1-area-0.0.0.0] quit
[VTEP2-ospf-1] quit

    # After OSPF is configured, VTEP1, VTEP2, and VTEP3 can learn the loopback interface address of each other and successfully ping each other. The following shows the result when VTEP2 pings VTEP1.

    [VTEP2] ping 10.1.1.1
