If this VRRP switch fails, another VRRP standby switch automatically takes over as master. The physical VRRP switch that forwards packets at any given time is the master. VRRP allows two or more network devices in an active or standby configuration to share a single virtual default gateway. With the virtual MAC active on both MLAG devices, either MLAG device handles the frame it receives. If the destination of this frame is the virtual MAC address and you are running VRRP, the frame can go to the link connected to the VRRP standby device, which does not forward the frame to the right destination. A device that connects to an MLAG bond believes there is a single device on the other end of the bond and only forwards one copy of the transit frames. Use VRR when you connect multiple devices to a single logical connection, such as an MLAG bond. The switches respond in an identical manner, but if one fails, the other redundant switches continue to respond. Redundant switches respond to ARP requests from hosts. VRR enables hosts to communicate with any redundant switch without reconfiguration by running dynamic router protocols or router redundancy protocols.
