Number of virtual IP addresses of VRRP groups that can be configured on the USG6000

Example for configuring VRRP load balancing (configuring multiple virtual IP addresses)
Requirements:
USG_A serves as the Master of VRRP group 1 and the Backup of VRRP group 2.
USG_B serves as the Master of VRRP group 2 and the Backup of VRRP group 1.
On the internal network, HostA uses VRRP group 1 as the gateway, and HostC uses VRRP group 2 as the gateway. This helps implement load balancing and mutual backup.
Configuration roadmap
1. Create two VRRP groups at GigabitEthernet 0/0/2 of USG_A. USG_A serves as the Master of VRRP group 1 and the Backup of VRRP group 2.
2. Create two VRRP groups at GigabitEthernet 0/0/2 of USG_B. USG_B serves as the Backup of VRRP group 1 and the Master of VRRP group 2.
Operation steps
1. Configure VRRP.
# Configure GigabitEthernet0/0/2 on USG_A, create VRRP group 1, and set the priority of USG_A in VRRP group 1 to 105 (as the Master). Create VRRP group 2 and set the priority of USG_A in VRRP group 2 to the default value 100 (as the Backup).
