Multiple VRRP Group Configuration Example
Network requirements
• In the network, some hosts use 1::10/64 as their default gateway and some hosts use 1::20/64 as
their default gateway.
• Load sharing and mutual backup between default gateways can be implemented by using VRRP
groups.

Configuration procedure
Step1 Configure Device A
system-view
[DeviceA] ipv6
[DeviceA] interface gigabitethernet 0/1
[DeviceA-GigabitEthernet0/1] ipv6 address fe80::1 link-local
[DeviceA-GigabitEthernet0/1] ipv6 address 1::1 64
# Create VRRP group 1 and set its virtual IPv6 addresses to FE80::10 and 1::10.
[DeviceA-GigabitEthernet0/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[DeviceA-GigabitEthernet0/1] vrrp ipv6 vrid 1 virtual-ip 1::10
# Set the priority of Device A in VRRP group 1 to 110.
[DeviceA-GigabitEthernet0/1] vrrp ipv6 vrid 1 priority 110
# Create VRRP group 2 set its virtual IPv6 addresses to FE80::20 and 1::20.
[DeviceA-GigabitEthernet0/1] vrrp ipv6 vrid 2 virtual-ip fe80::20 link-local
[DeviceA-GigabitEthernet0/1] vrrp ipv6 vrid 2 virtual-ip 1::20
# Enable Device A to send RA messages.
[DeviceA-GigabitEthernet0/1] undo ipv6 nd ra halt
