Configuration procedure
1. Configure Router A:
<RouterA> system-view
[RouterA] interface GigabitEthernet 4/1/1
[RouterA-GigabitEthernet4/1/1] 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.
[RouterA-GigabitEthernet4/1/1] vrrp vrid 1 virtual-ip 202.38.160.111
# Configure the priority of Router A in the VRRP group 1 as 110, which is higher than that of Router
B (100), so that Router A can become the master.
[RouterA-GigabitEthernet4/1/1] vrrp vrid 1 priority 110
# Configure Router A to work in preemptive mode so that it can become the master whenever it
works normally. Configure the preemption delay as five seconds to avoid frequent status
switchover.
[RouterA-GigabitEthernet4/1/1] vrrp vrid 1 preempt-mode timer delay 5
2. Configure Router B:
<RouterB> system-view
[RouterB] interface GigabitEthernet 4/1/1
[RouterB-GigabitEthernet4/1/1] 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.
[RouterB-GigabitEthernet4/1/1] vrrp vrid 1 virtual-ip 202.38.160.111
# Configure Router B to work in the preemptive mode, with the preemption delay set to 5 seconds.
[RouterB-GigabitEthernet4/1/1] vrrp vrid 1 preempt-mode timer delay 5
3. 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 the detailed information of VRRP group 1 on Router A.
[RouterA-GigabitEthernet4/1/1] display vrrp verbose
