92BSingle VRRP group configuration example (at the CLI)

254BNetwork requirements

• Host A needs to access Host B on the Internet, using 202.38.160.111/24 as its default gateway.

• Firewall A and Firewall B belong to VRRP group 1 with the virtual IP address of 202.38.160.111/24.

• If Firewall A operates normally, packets sent from Host A to Host B are forwarded by Firewall A. If

Firewall A fails, packets sent from Host A to Host B are forwarded by Firewall B.

255BConfiguration procedure

1. Configure Firewall A:

<FirewallA> system-view

[FirewallA] interface gigabitethernet 0/1

[FirewallA-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.

[FirewallA-GigabitEthernet0/1] vrrp vrid 1 virtual-ip 202.38.160.111

# Configure the priority of Firewall A in the VRRP group 1 as 110, which is higher than that of

Firewall B (100), so that Firewall A can become the master.

[FirewallA-GigabitEthernet0/1] vrrp vrid 1 priority 110

# Configure Firewall A to operate 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.

[FirewallA-GigabitEthernet0/1] vrrp vrid 1 preempt-mode timer delay 5

2. Configure Firewall B:

<FirewallB> system-view

[FirewallB] interface gigabitethernet 0/1

[FirewallB-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.

[FirewallB-GigabitEthernet0/1] vrrp vrid 1 virtual-ip 202.38.160.111

# Configure Firewall B to operate in preemptive mode, with the preemption delay set to five

seconds.

[FirewallB-GigabitEthernet0/1] vrrp vrid 1 preempt-mode timer delay 5
