Example: Configuring DRNI and VRRP

Network configuration

In the underlay network as shown in Figure 1, deploy DRNI at the access layer to provide high

availability and load balancing services for access devices. Deploy VRRP to provide gateway

redundancy and ensure user service continuity. You can achieve the following purposes on the

server through the VRRP gateway:

•

To implement Layer 2 connectivity, the server can communicate with the service network at

Layer 2 through the DR system.

•

Use the secondary IP addresses of the VLAN interfaces created on the DR member devices to

set up Layer 3 links between the server and the core devices, and configure BGP or OSPF to

achieve Layer 3 connectivity.

Analysis

•

Deploy link aggregation between DRNI 1 and the server and between DRNI 2 and the server.

•

Deploy DRNI for DRNI 1 and DRNI 2 at the access layer. Configure a VRRP group and specify

its virtual IP address as the gateway address of the server.

•

Core 1 and Core 2 are Layer 3 devices connected to the service network.

•

Create VLAN interfaces on the DR interfaces of the DR member devices, and configure the

primary and secondary IP addresses.

 Set up Layer 3 links between the DR member devices and the core devices, and configure

BGP between them to achieve Layer 3 connectivity.

 Use the secondary IP address of the VLAN interfaces created on the DR interfaces to set

up Layer 3 links to the server, and configure BGP or OSPF to achieve Layer 3 connectivity.

Upgrading the devices

Upgrading the DR member devices

Checking the environment

Execute the commands in "Verification commands" and the following commands to verify that the

device is available for an upgrade.

DRNI 1 DRNI 2 Description

display device

Displays device information.

display boot-loader display boot-loader Displays current software images and

startup software images.

display version

Displays system version information.

Upgrading the device

1. Use the display version command to verify the current BootWare image version and

startup software version.

2. Use the release notes for the upgrade software version to evaluate the upgrade impact on your

network and verify the following items:

 Software and hardware compatibility.

 Version and size of the upgrade software.

 Compatibility of the upgrade software with the current BootWare image and startup

software image.

3. Use the dir command to verify that the device has sufficient storage space for the upgrade

images. If the storage space is not sufficient, delete unused files by using the delete

command. Verify that each MPU in the system has sufficient storage space.

4. Use FTP or TFTP to transfer the upgrade image file to the root directory of a file system.

5. Upgrade the device according to the configuration guides for the device.

Verifying the traffic interruption time during the upgrade

Verify that the traffic interruption time is shorter than 500 ms during a switchover and shorter than

150 ms during fallback. For more information, see "Testing network convergence."

Verifying the upgrade result

Execute the commands in "Verification commands" and the following commands to verify that the

device is upgraded successfully.

Adding the device to the DR system

1. Disconnect the device from network management systems.

2. Upgrade the software of the device as needed.

3. Preconfigure the device.

4. Connect the device to network management systems.

5. Incorporate the device on the controller.

Verifying the traffic interruption time

For more information, see "Testing network convergence."

Verifying the expansion result

Execute the following commands to verify that the device is added successfully.

Replacing a service module

1. Switch service and management traffic on the target service module to other service modules.

2. Power off the device and replace the service module, or replace the service module when the

device is running. For more information, see the installation guides for the service module.

Verifying the traffic interruption time

For more information, see "Testing network convergence."

Verifying the replacement result

Execute the commands in "Checking the environment."
