Introduction

The following information provides an example for software upgrade with zero packet loss by using GIR in a VXLAN M-LAG network.

Prerequisites

This document is not restricted to specific software or hardware versions. Procedures and information in the examples might be slightly different depending on the software or hardware version of the device.

The configuration examples 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.

The following information is provided based on the assumption that you have basic knowledge of VXLAN and GIR.

Network configuration

As shown in Figure 1:

·     Device A and Device B act as distributed VXLAN IP gateways connected to Device E. Device A and Device B form an M-LAG system to act as a virtual VXLAN IP gateway and use a directly connected link as the peer link. Device E belongs to VXLAN 10.

·     Device C and Device D act as distributed VXLAN IP gateways connected to Device F. Device C and Device D form an M-LAG system to act as a virtual VXLAN IP gateway and use a directly connected link as the peer link. Device F belongs to VXLAN 20.

·     Configure Device B to enter maintenance mode and switch traffic to Device A. After Device B completes its upgrade, switch traffic back to Device B and then upgrade Device A.

·     Configure Device D to enter maintenance mode and switch traffic to Device C. After Device D completes its upgrade, switch traffic back to Device D and then upgrade Device C.

Analysis

·     Device A and Device B form one M-LAG system. Device C and Device D form another M-LAG system.

·     Configure Device A, Device B, Device C, and Device D as VTEPs and configure Device E as the core device.

·     First use GIR to isolate and upgrade the secondary device (Device B), and then use GIR to isolate and upgrade the primary device (Device A).

·     First use GIR to isolate and upgrade the secondary device (Device D), and then use GIR to isolate and upgrade the primary device (Device C).

Restrictions and guidelines

When using GIR to upgrade or replace devices in an M-LAG network, follow these restrictions and guidelines:

·     As a best practice, do not configure isolation separately for route and aggregation services to avoid issues like packet loss due to configuration omissions.

·     When specifying the next startup configuration file, include maintenance mode settings in the file.

Procedures

Configuring IPv4 VXLAN M-LAG

1.     Configure IP addresses and unicast routing protocols:

# Configure the IP address and subnet mask for each interface. (Details not shown.)

# Configure routes on the IP transport network to advertise routes for subnets attached to the interfaces (including Loopback interfaces) on each node. Make sure the devices have connectivity to each other. (Details not shown.)

2.     Configure Device A:

# Enable Layer 2 VPN (L2VPN).

<DeviceA> system-view

[DeviceA] l2vpn enable

# Configure the frame match criteria for dynamic ACs on the peer link, with in one of the following methods. You must configure Device A and Device B in the same method.

¡     Method 1: Create the frame match criteria of dynamic ACs on the peer link based on VXLAN IDs.

[DeviceA] l2vpn m-lag peer-link ac-match-rule vxlan-mapping

¡     Method 2: Create an AC on the peer link based on the frame match criteria of the site-facing Ethernet service instance.

You do not need to configure other settings. This method is used by default.

5.     After traffic switchback completes, identify whether the service is operating correctly:

You can identify whether the service is operating correctly in either of the following methods:

¡     Compare the collected entries (such as the routing table, FIB table, and MAC address table entries) with those before the upgrade to check for any losses. Compare the service traffic before and after the upgrade to ensure consistency.

¡     Together with maintenance staff, identify whether service is operating properly and servers are operating correctly.

6.     Identify whether the device is in normal mode.

7.     Save the configuration. The secondary device upgrade is complete.

Upgrading the primary device (Device A)

Upgrade Device A following the steps in "Upgrading the secondary device (Device B)." (Details not shown.)

Upgrading the secondary device (Device D)

Upgrade Device D following the steps in “Upgrading the secondary device (Device B)." (Details not shown.)

Upgrading the primary device (Device C)

Upgrade Device C following the steps in "Upgrading the secondary device (Device B)." (Details not shown.)

Replacing a faulty M-LAG member device

If you need a shorter convergence time and the faulty device can be switched to maintenance mode for replacement, follow these steps to replace it:

1.     Execute the gir system-mode maintenance command on the faulty device to switch the device from normal mode to maintenance mode and save the configuration.

2.     Import the faulty device's configuration file to the new device.

3.     Specify the image file and configuration file on the new device, and then reboot the device to apply the image file and configuration file.

4.     Power off the new device or shut down all physical interfaces.

5.     Shut down all physical interfaces on the faulty device or power off the faulty device. (When replacing multiple devices, power off the devices as a best practice.)

6.     Replace the faulty device.

7.     Connect the cables to the new device.

8.     Power on the new device or bring up all physical interfaces.

9.     Execute the undo gir system-mode maintenance command on the new device to switch from maintenance mode to normal mode and save the configuration.

2.     Verify that hosts can access each other

VMs Device E and Device F can access each other. If Device E disconnects from Device A or Device B, Device E and Device F can still communicate through another device.

3.     Verify packet loss during an upgrade

During the upgrade of Device A, monitor the packet loss in traffic between Device G and Device E. Empirical data shows no packet loss occurs between them.
