[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] vrrp mode load-balance
# Create VRRP group 1 and configure its virtual IPv6 addresses as FE80::10 and 1::10.

[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.

# Set Router B to operate in preemptive mode. The preemption delay is 5 seconds.

# Enable Router B to send RA messages, so that hosts in network segment 1::/64 can learn the
default gateway address.

# Create VRRP group 1 and configure its virtual IPv6 addresses as FE80::10 and 1::10.
