Setting up a VIP group
In symmetric configurations with Virtual Router Redundancy Protocol Extended (VRRP-E), when the
device switches from active to standby state, you can enable simultaneous VIP failover if the
VRRP-E fails over to a standby device. To enable this feature, you must define a VIP group with
several VIP addresses and bind the VIP group to a virtual router ID (VRID).
To set up a VIP group on the device, perform the following steps with the Configure tab.
1. Click System on the menu bar.
2. From the sidebar, select High Availability, and then select VIP Groups.
The Summary page is displayed, as shown in Figure 11.
