The VRRP protocol

Kaspersky SD-WAN supports installing CPE devices at on locations to ensure high availability of these locations. One option for organizing high availability is to use the Virtual Router Redundancy Protocol (VRRP). You can configure VRRP between multiple CPE devices, or between a device and a third-party router.

When configuring VRRP, you must create VRRP instances that specify which CPE devices are combined into virtual routers for high availability.

Each VRRP instance is created with general VRRP settings such as the Virtual Router Identifier (VRID) and the virtual IP address for the network interface of the CPE device.

VRRP instances can be combined into groups to synchronize their operation. In this way, if a change to the primary VRRP router occurs in one of the VRRP instances within the group, the same change is also applied to all other VRRP instances in the group.
