This document provides Virtual eXtensible LAN (VXLAN) configuration examples. VXLAN is a MAC-in-UDP technology that provides Layer 2 connectivity between distant network sites across an IP network. VXLAN is typically used in data centers for multitenant services.

Prerequisites

This document is not restricted to specific software or hardware versions.

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of VXLAN.

General restrictions and guidelines

Restrictions and guidelines for the S6520XE-HI switch series

Before you configure VXLAN settings, perform the following tasks:

1. Execute the switch-mode command in system view to set the table capacity mode to 0, 2, 3, or 5.

2. Save the running configuration to the next-startup configuration file.

3. Reboot the device.

For more information about the table capacity mode, see device management in Fundamentals Configuration Guide.

Restrictions and guidelines for the S5560X-EI switch series

Before you configure VXLAN settings, perform the following tasks:

1. Execute the switch-mode 1 command in system view to set the system operating mode to VXLAN.

2. Save the running configuration to the next-startup configuration file.

3. Reboot the device.

For more information about the system operating mode, see device management in Fundamentals Configuration Guide.

Example: Configuring VXLAN Layer 2 forwarding

Network configuration

As shown in Figure 1:

· Configure VXLAN 10 as a unicast-mode VXLAN on Switch A, Switch B, and Switch C to provide Layer 2 connectivity for the VMs across the network sites.

· Manually establish VXLAN tunnels and assign the tunnels to VXLAN 10.

Figure 1 Network diagram

Analysis

To ensure that the switches in the transport network can reach one another, configure a routing protocol on the switches to advertise routes for interfaces, including the loopback interfaces. In this example, OSPF is used.

To assign Switch A, Switch B, and Switch C to a VXLAN network, create VXLAN tunnels on the switches and assign the tunnels to the VXLAN.

To assign the customer traffic of a VLAN to a VXLAN, you must perform the following tasks:

· Create an Ethernet service instance on the interface that receives the traffic.

· Configure the Ethernet service instance to match the VLAN.

· Map the Ethernet service instance to the VSI on which the VXLAN is created.

Example: Configuring a centralized VXLAN IP gateway

Network configuration

As shown in Figure 2:

· Configure VXLAN 10 and VXLAN 20 as unicast-mode VXLANs on Switch A, Switch B, and Switch C.

· Manually establish VXLAN tunnels and assign the tunnels to VXLAN 10 or VXLAN 20. Make sure VM 1 and VM 3 belong to VXLAN 10 and VM 2 and VM 4 belong to VXLAN 20.

· Configure a centralized VXLAN IP gateway on Switch C to provide gateway services for VXLAN 10 and VXLAN 20.

Figure 2 Network diagram

Analysis

To assign Switch A, Switch B, and Switch C to VXLANs, create VXLAN tunnels on the switches and assign the tunnels to the VXLANs.

To assign the customer traffic of a VLAN to a VXLAN on Switch A or Switch B, you must perform the following tasks:

· Create an Ethernet service instance on the interface that receives the traffic.

· Configure the Ethernet service instance to match the VLAN.

· Map the Ethernet service instance to the VSI on which the VXLAN is created.

For Switch C to provide centralized VXLAN IP gateway services for VXLANs, you must perform the following tasks:

· Create a VSI interface for each VXLAN on the switch.

· Assign an IP address to each VSI interface.

· Specify the VSI interfaces as the gateway interfaces for VXLANs.

For Layer 3 nodes in the transport network to reach the VMs, configure a routing protocol on Switch C to advertise routes for VSI interfaces and VLAN-interface 100. In this example, OSPF is used.
