3. Configure a track entry on Router A:
# Configure track entry 1, and associate it with reaction entry 1 of the NQA test group (with the
administrator admin, and the operation tag test).
[RouterA] track 1 nqa entry admin test reaction 1
4. Configure VRRP on Router A:
# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.
[RouterA] interface GigabitEthernet 3/1/10
[RouterA-GigabitEthernet3/1/10] vrrp vrid 1 virtual-ip 10.1.1.10
# Set the priority of Router A in VRRP group 1 to 110.
[RouterA-GigabitEthernet3/1/10] vrrp vrid 1 priority 110
# Set the authentication mode of VRRP group 1 to simple, and the authentication key to hello.
[RouterA-GigabitEthernet3/1/10] vrrp vrid 1 authentication-mode simple hello
# Configure the master to send VRRP packets at an interval of five seconds.
[RouterA-GigabitEthernet3/1/10] vrrp vrid 1 timer advertise 5
# Configure Router A to work in preemptive mode, and set the preemption delay to five seconds.
[RouterA-GigabitEthernet3/1/10] vrrp vrid 1 preempt-mode timer delay 5
# Configure to monitor track entry 1 and specify the priority decrement to 30.
[RouterA-GigabitEthernet3/1/10] vrrp vrid 1 track 1 reduced 30
5. Configure VRRP on Router B:
system-view
[RouterB] interface GigabitEthernet 3/1/10
# Create VRRP group 1, and configure the virtual IP address 10.1.1.10 for the group.
[RouterB-GigabitEthernet3/1/10] vrrp vrid 1 virtual-ip 10.1.1.10
# Set the authentication mode of VRRP group 1 to simple, and the authentication key to hello.
[RouterB-GigabitEthernet3/1/10] vrrp vrid 1 authentication-mode simple hello
# Configure the master to send VRRP packets at an interval of five seconds.
[RouterB-GigabitEthernet3/1/10] vrrp vrid 1 timer advertise 5
# Configure Router B to work in preemptive mode, and set the preemption delay to five seconds.
[RouterB-GigabitEthernet3/1/10] vrrp vrid 1 preempt-mode timer delay 5
Verifying the configuration
After configuration, ping Host B on Host A, and you can see that Host B is reachable. To view the
configuration result, use the display vrrp command.
# Display detailed information about VRRP group 1 on Router A.
