A router can be in multiple VRRP groups and hold a different priority in different group.
In
Figure 5 , three VRRP groups are present:
• VRRP group 1: Router A is the master; Router B and Router C are the backups.
• VRRP group 2: Router B is the master; Router A and Router C are the backups.
• VRRP group 3: Router C is the master; Router A and Router B are the backups.
To balance load among Router A, Router B, and Router C, configure hosts on the LAN to use VRRP group
1, 2, and 3 as the default gateways respectively. When configuring VRRP priorities, make sure that each
router holds such a priority in each VRRP group that it will take the expected role in the group.
Configuring VRRP
Configuration Task List
Perform the tasks in Table 1 to configure VRRP.
Table 1 VRRP configuration task list
Task Remarks
Creating a VRRP Group
Required
Create a VRRP group on a VRRP interface and configure the virtual IP
address.
IMPORTANT:
z Before creating a VRRP group on an interface, you should first
configure an IP address for the interface and ensure that the virtual IP
address to be configured is in the same network segment as the IP
address of the interface.
z Up to 16 VRRP groups can be created on an interface.
z Up to 16 virtual IP addresses can be configured in a VRRP group.
Configuring a VRRP Group
Optional
Configure router priority, preemption mode, authentication mode, packet
attributes, and tracking function of the VRRP group.
Creating a VRRP Group
Select High Reliability > VRRP from the navigation tree to enter the VRRP interfaces page, as shown
in
Figure 6 . Click the icon corresponding to the interface to be configured to enter the VRRP
Configuration on Interface page, as shown in Figure 7 . Click Add to enter the Create VRRP
Group page.
