[SysnameA-vlan2] quit
[SysnameA] interface vlan-interface 2
[SysnameA-Vlan-interface2] ipv6 address fe80::1 link-local
[SysnameA-Vlan-interface2] ipv6 address 1::1 64
# Create a standby group 1 and set its virtual IP address to fe80::10.
[SysnameA-Vlan-interface2] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local

3 Verify the configuration
After the configuration, Host B can be pinged through on Host A. You can use the
display vrrp ipv6 command to verify the configuration.
