We can see that Switch A and Switch B are in IPv6 VRRP backup group 1 pointing to
the same IPv6 address (2000::1) of virtual router and operating in VRRP preemptive
mode. Since the priority of Switch A in IPv6 VRRP backup group is 120 and the priority
of Switch B in VRRP backup group is 100 (default value), Switch A will act as the
Master router of IPv6 VRRP under normal conditions.
