4. Configure VRRP on Switch A:
# Specify VRRPv2 to run on VLAN-interface 2.
[SwitchA] interface vlan-interface 2
[SwitchA-Vlan-interface2] vrrp version 2
# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.
[SwitchA-Vlan-interface2] vrrp vrid 1 virtual-ip 10.1.1.10
# Set the priority of Switch A to 110 in VRRP group 1.
[SwitchA-Vlan-interface2] vrrp vrid 1 priority 110
# Set the authentication mode of VRRP group 1 to simple, and the authentication key to hello.
[SwitchA-Vlan-interface2] vrrp vrid 1 authentication-mode simple hello
# Configure the master to send VRRP packets at an interval of 500 centiseconds.
[SwitchA-Vlan-interface2] vrrp vrid 1 timer advertise 500
# Configure Switch A to operate in preemptive mode and set the preemption delay to 500
centiseconds.
[SwitchA-Vlan-interface2] vrrp vrid 1 preempt-mode delay 500
# Configure to monitor track entry 1 and decrease the router priority by 30 when the state of
track entry 1 changes to negative.

5. Configure VRRP on Switch B:
# Specify VRRPv2 to run on VLAN-interface 2.
<SwitchB> system-view
[SwitchB] interface vlan-interface 2
