[RouterA] track 1 interface ethernet 1/2
# Configure VF tracking to monitor track entry 1 and specify the value by which the weight
decreases, making the weight of Router A decrease by more than 245 (250 in this example) when
track entry 1 turns to negative. In such a case, another router with a higher weight can take over.

2. Configure Router B:
# Configure VRRP to operate in load balancing mode.
<RouterB> system-view
[RouterB] vrrp mode load-balance
# Create VRRP group 1 and configure its virtual IPv6 addresses as FE80::10 and 1::10.
[RouterB] interface ethernet 1/1
[RouterB-Ethernet1/1] ipv6 address fe80::2 link-local
[RouterB-Ethernet1/1] ipv6 address 1::2 64
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip 1::10
# Set the priority of Router B in VRRP group 1 to 110, which is higher than that of Router C (100)
so that Router B can become the master when Router A fails.
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 priority 110
# Set Router B to operate in preemptive mode. The preemption delay is 5 seconds.
[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 preempt-mode timer delay 5
# Enable Router B to send RA messages, so that hosts in network segment 1::/64 can learn the
default gateway address.
[RouterB-Ethernet1/1] undo ipv6 nd ra halt
[RouterB-Ethernet1/1] quit
# Create track entry 1 to associate with the physical status of Ethernet 1/2 on Router B. When the
track entry becomes negative, it means that the interface fails.
[RouterB] track 1 interface ethernet 1/2
# Configure VF tracking to monitor track entry 1 and specify the value by which the weight
decreases, making the weight of Router B decrease by more than 245 (250 in this example) when
track entry 1 turns to negative. In such a case, another router with a higher weight can take over.

[RouterB-Ethernet1/1] vrrp ipv6 vrid 1 weight track 1 reduced 250
3. Configure Router C:
# Configure VRRP to operate in load balancing mode.
<RouterC> system-view
[RouterC] vrrp mode load-balance
# Create VRRP group 1 and configure its virtual IPv6 addresses as FE80::10 and 1::10.
[RouterC] interface ethernet 1/1
[RouterC-Ethernet1/1] ipv6 address fe80::3 link-local
[RouterC-Ethernet1/1] ipv6 address 1::3 64
[RouterC-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip fe80::10 link-local
[RouterC-Ethernet1/1] vrrp ipv6 vrid 1 virtual-ip 1::10
# Set Router C to operate in preemptive mode and set the preemption delay to 5 seconds.
[RouterC-Ethernet1/1] vrrp ipv6 vrid 1 preempt-mode timer delay 5
