Operating

VRRP – Virtual Router Redundancy Protocol – enables multiple physical routers to appear as a single "virtual" router. Of the existing physical routers, one is always the "master". The master is the only router that establishes a data connection to the Internet, for example, and transfers data. Only when the master fails, for example as a result of a power outage or if its Internet connection is dropped, will the other routers become active. They will then negotiate with the VRRP protocol to determine which router should assume the role of master. The new master completely takes over the tasks that were carried out by the previous master.
