• If Device A operates normally, packets sent from Host A to Host B are forwarded by Device A; if
Device A fails, packets sent from Host A to Host B are forwarded by Device B.

Configuration procedure
Step1 Configure Device A
system-view
[DeviceA] interface gigabitethernet 0/1
[DeviceA-GigabitEthernet0/1] ip address 202.38.160.1 255.255.255.0
# Create VRRP group 1 and configure its virtual IP address as 202.38.160.111.
[DeviceA-GigabitEthernet0/1] vrrp vrid 1 virtual-ip 202.38.160.111
# Configure the priority of Device A in the VRRP group 1 as 110.
[DeviceA-GigabitEthernet0/1] vrrp vrid 1 priority 110
# Configure Device A to work in preemptive mode and configure the preemption delay as five seconds.
[DeviceA-GigabitEthernet0/1] vrrp vrid 1 preempt-mode timer delay 5
Step2 Configure Device B
system-view
[DeviceB] interface gigabitethernet 0/1
[DeviceB-GigabitEthernet0/1] ip address 202.38.160.2 255.255.255.0
# Create VRRP group 1 and configure its virtual IP address as 202.38.160.111.
[DeviceB-GigabitEthernet0/1] vrrp vrid 1 virtual-ip 202.38.160.111
# Configure Device B to work in the preemptive mode, with the preemption delay set to 5 seconds.
[DeviceB-GigabitEthernet0/1] vrrp vrid 1 preempt-mode timer delay 5
Step3 Verify the configuration
After the configuration, Host B can be pinged successfully on Host A. To verify your configuration, use the
display vrrp verbose command.
# Display detailed information of VRRP group 1 on Device A.
[DeviceA-GigabitEthernet0/1] display vrrp verbose
