Example: Configuring IPv4 and IPv6

dual-active VLAN gateways on a DRNI

network

Network configuration

As shown in Figure 1:

•

Device A and Device B form a DR system. Device D accesses the DR system through DR

interfaces.

•

Device A and Device B are connected to uplink device Device C through equal-cost routes.

Configure the network as follows to meet the server access requirements of users:

•

The two DR member devices Device A and Device B both act as the IPv4 gateway and IPv6

gateway for the servers.

•

If the link between Device A or Device B and uplink device Device C fails, packets can be

transmitted along the other DR member device to Device C to avoid interrupting the servers’

communication with the external network.

In some scenarios, the devices or servers attached to the DR interfaces are required to establish

routing peer relationships with the DR member devices.

Analysis

•

Configure VLAN-interface 100 on Device A and Device B to act as the IPv4 and IPv6

dual-active gateways. To enable IPv4 and IPv6 users to access the external network through

the gateways, configure the same IPv4 address, MAC address, IPv6 address, and IPv6

link-local address for VLAN-interface 100 on Device A and Device B.

•

Enable Device A and Device B to communicate at Layer 3 through VLAN-interface 101. Then,

packets can be routed to the other DR member device when the link between Device A or

Device B and uplink device Device C fails.

Restrictions and guidelines

All the devices were started with the factory default configuration. When you are working on a live

network, make sure the existing configuration does not conflict with the following configuration.

The DR system MAC address must be the same for devices in the same DR system. The DR system

MAC addresses must be different for devices in different DR systems.

Traffic forwarding models

Underlay traffic characteristics

The forwarding model matrix provides the following characteristics of underlay traffic:

•

No.—Traffic number in the U-X-XXX format:

 U—Underlay traffic.

 X—Protocol number, which can be 4 (IPv4) or 6 (IPv6).

 XXX—Traffic sequence number.

•

Traffic type—Type of underlay traffic, which can be IPv4 known unicast or IPv6 known unicast.

•

Direction—Direction of underlay traffic.

•

Forwarding path—Nodes that underlay traffic traverses.

•

Traffic simulation—Traffic simulation method. Typically a tester is used to simulate server

traffic.

•

Load—Traffic size, which can be light (less than 1000 flows) and heavy (more than 1000 flows).

•

Traffic direction to firewalls/LB—Configuration used to direct traffic to firewalls and load

balancers, other than PBR, DRNI, VRRP, static routes.

Verifying that Server 1 and Server 2 can communicate with Network

Server 1 and Server 2 can communicate with Network through both IPv4 and IPv6 addresses.

Verifying that Server 1 and Server 2 can still communicate with Network when the uplink

interface of Device A or Device B fails

Disconnect the interface connecting Device A to Device C. Server 1 and Server 2 can still

communicate with Network (transient packet loss occurs during the traffic switchover process).

Upgrading the devices

Upgrading the DR member devices

Checking the environment

Execute the commands in "Verifying the configuration" and the following commands to verify that the

devices are 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 devices

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 when the traffic load is light. For more information, see “Testing network

convergence upon single points of failure.”

Verifying the upgrade result

Execute the commands in "Verifying the configuration" and the following commands to verify that the

device is upgraded successfully.
