Example for Configuring VRRP6 in Load Balancing Mode

Networking Requirements

• Switch A is the master device in VRRP group 1 and the backup device in VRRP group 2.

• Switch B is the master device in VRRP group 2 and the backup device in VRRP group 1.

• Host A on the LAN uses the virtual IPv6 address of VRRP group 1 as the gateway address, and Host B uses the virtual IPv6 address of VRRP group 2 as the gateway address. The two VRRP groups load balance traffic and back up each other.

Configuration Roadmap

The configuration roadmap is as follows:

1. Create VRRP group 1 and VRRP group 2 on VLANIF 100 of Switch A. Ensure that Switch A is the master device in VRRP group 1 and the backup device in VRRP group 2.

2. Create VRRP group 1 and VRRP group 2 on VLANIF 100 of Switch B. Ensure that Switch B is the backup device in VRRP group 1 and the master device in VRRP group 1.

Data Preparation

To complete the configuration, you need the following data:

• IPv6 addresses of the interfaces

• IDs and virtual IPv6 addresses of the VRRP groups

• Priorities of the switches in each VRRP group

Procedure

1. Configure IP addresses for the interfaces. The configuration procedure is not mentioned here.

2. Configure OSPFv3 on Switch A, Switch B, and Switch C so that they can communicate with each other. The configuration procedure is not mentioned here.

3. Configure the hosts.

   Set the default gateway address of Host A to 2000::10, which is the virtual IPv6 address of VRRP group 1. Set the default gateway address of Host B to 2000::60, which is the virtual IPv6 address of VRRP group 2. Set the default gateway address of Host C to 2003::2.

4. Configure VRRP6 groups.

   # Create VRRP group 1 and VRRP group 2 on VLANIF 100 of Switch A. Set the priority of Switch A in VRRP group 1 to 120 so that Switch A becomes the master device in VRRP group 1. Use the default priority of Switch A in VRRP group 2 so that Switch A becomes the backup device in VRRP group 2.

# Create VRRP group 1 and VRRP group 2 on VLANIF 100 of Switch B. Use the priority of Switch B in VRRP group 1 to 120 so that Switch B becomes the backup device in VRRP group 1. Set the priority of Switch B in VRRP group 2 to 120 so that Switch B becomes the master device in VRRP group 2.

[SwitchB-Vlanif100] vrrp6 vrid 2 priority 120
[SwitchB-Vlanif100] quit

5. Verify the configuration.

After the preceding configuration is complete, Host A and Host C can ping Host B successfully. Run the display vrrp6 command on Switch A, and you can find that VRRP group 1 and VRRP group 2 are created on Switch A. Switch A is the master device in VRRP group 1 and the backup device in VRRP group 2.
