12.1.1 Introduction to VRRP Group
During data communication process, software and hardware error may result network disconnection, causing data
transmission failure. To avoid data communication disconnected, DPtech FW has provides Virtual Router
Redundancy Protocol (VRRP) technology using back up solution when communication line or device failure, so
that it ensure data communication smoothly and enhance network robustness and availability.
Enhancing local network and outside network connection availability, VRRP is fit for the local area network
which support multicast and broadcast (such as Ethernet). Through many devices forming a back up group, they
have an exit gateway for the local network and they are all transparent inside the local network. In the back up group,
if an FW device failure, it will be substituted by other device. So that the local host can still work without any
modification, greatly enhance network communication availability.
