You are planning an Active-Active-Active VRRP-A three-device deployment that, upon failover of any device, distributes the load from a single device to both standby devices simultaneously. How many VRIDs are required?

A. B. C. D. E. F.C -
Virtual Router Redundancy Protocol (VRRP) is a protocol that provides redundancy for IP networks by allowing multiple routers to participate in a virtual router that shares a virtual IP address. VRRP-A (VRRP Advanced) is an extension to VRRP that allows for load balancing among the virtual router group members in an active-active-active setup. In this setup, all the devices in the VRRP-A group actively forward packets simultaneously and share the traffic load.
To answer the question, we need to determine how many Virtual Router IDs (VRIDs) are required for this Active-Active-Active VRRP-A deployment. A VRID is a unique identifier that is assigned to each VRRP instance to differentiate it from other VRRP instances running on the same LAN segment. Each VRRP instance is assigned a different VRID.
In an Active-Active-Active VRRP-A setup, there are three devices, and each device is configured as an active router. When any one of the devices fails, the load needs to be distributed to the remaining two standby devices. To achieve this, we need to configure three different VRIDs, one for each device. Each VRID will be active on the device that is associated with it. When any one of the devices fails, the VRID associated with the failed device will be moved to one of the standby devices, and the traffic load will be shared between the remaining two devices. Therefore, we require three VRIDs to achieve this level of redundancy and load sharing.
Therefore, the correct answer is E. 3.
