# Set VLAN interface 3 on AC 1 to be tracked, and configure the amount by which the priority
value decreases to be more than 10 (30 in this example), so that when VLAN-interface 3 fails, the
priority of AC 1 in VRRP group 1 decreases to a value lower than 100 and thus AC 2 can become
the master.

3. Configure AC 2:
# Configure VLAN 2.

[AC2-vlan2] quit
[AC2] interface WLAN-ESS 1
[AC2-WLAN-ESS1] port link-type hybrid
[AC2-WLAN-ESS1] undo port hybrid vlan 1
[AC2-WLAN-ESS1] port hybrid vlan 2 untagged
[AC2-WLAN-ESS1] port hybrid pvid vlan 2
[AC2-WLAN-ESS1] quit
[AC2] interface vlan-interface 2
[AC2-Vlan-interface2] ip address 202.38.160.2 255.255.255.0
# Create a VRRP group 1 on VLAN-interface 2 and set its virtual IP address to 202.38.160.111.
[AC2-Vlan-interface2] vrrp vrid 1 virtual-ip 202.38.160.111
# Configure the authentication mode of the VRRP group as simple and authentication key as hello.
[AC2-Vlan-interface2] vrrp vrid 1 authentication-mode simple hello
# Set the interval for master to send VRRP advertisement to four seconds.
[AC2-Vlan-interface2] vrrp vrid 1 timer advertise 4
# Configure AC 2 to operate in preemptive mode, so that AC 2 can become the master after the
priority of AC 1 decreases to a value lower than 100. Configure the preemption delay as five
seconds to avoid frequent status switchover.

4. Verify the configuration:
# Ping the host from the client. (Details not shown.)
# Display information about VRRP group 1 on AC 1.
