Multiple VRRP groups configuration example

To implement load sharing between the VRRP groups, manually configure the default gateway 1::10 for some hosts and 1::20 for the other hosts on the subnet 1::/64.

Network requirements

As shown in Figure 27, Router A and Router B form two VRRP groups to implement load sharing and mutual backup. VRRP group 1 uses the virtual IP address 1::10/64 to provide gateway service for some hosts on the subnet 1::/64. VRRP group 2 uses the virtual IP address 1::20/64 to provide gateway service for the other hosts on the subnet.

Configuration procedure

  1. Configure Router A:

    # Specify an IPv6 address for Router A.

    <RouterA> system-view
    [RouterA] interface gigabitethernet 1/0/1
    [RouterA-GigabitEthernet1/0/1] ipv6 address fe80::1 link-local
    [RouterA-GigabitEthernet1/0/1] ipv6 address 1::1 64
    

    # Create VRRP group 1, and set its virtual IPv6 addresses to FE80::10 to 1::10.

    [RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
    [RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 virtual-ip 1::10
    

    # Assign a higher priority to Router A than Router B in VRRP group 1, so Router A can become the master in the group.

    [RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 priority 110
    

    # Create VRRP group 2, and set its virtual IPv6 addresses to FE80::20 and 1::20.

    [RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 2 virtual-ip fe80::20 link-local
    [RouterA-GigabitEthernet1/0/1] vrrp ipv6 vrid 2 virtual-ip 1::20
    
  2. Configure Router B:

    # Specify an IPv6 address for Router B.

    <RouterB> system-view
    [RouterB] interface gigabitethernet 1/0/1
    [RouterB-GigabitEthernet1/0/1] ipv6 address fe80::2 link-local
    [RouterB-GigabitEthernet1/0/1] ipv6 address 1::2 64
    

    # Create VRRP group 1, and set its virtual IPv6 addresses to FE80::10 and 1::10.

    [RouterB-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
    [RouterB-GigabitEthernet1/0/1] vrrp ipv6 vrid 1 virtual-ip 1::10
    

    # Create VRRP group 2, and set its virtual IPv6 addresses to FE80::20 and 1::20.

    [RouterB-GigabitEthernet1/0/1] vrrp ipv6 vrid 2 virtual-ip fe80::20 link-local
    [RouterB-GigabitEthernet1/0/1] vrrp ipv6 vrid 2 virtual-ip 1::20
    

    # Assign Router B a higher priority than Router A in VRRP group 2, so Router B can become the master in the group.

    [RouterB-GigabitEthernet1/0/1] vrrp ipv6 vrid 2 priority 110
