In the load balancing scenario, however, there are two different WAN connections online simultaneously, which is why the use of the same MAC and IP address is not possible here. In this case, a routing protocol such as RIP, OSPF or BGP must be used as a second option.
In order to accelerate the switch using RIP, which is rather slow, a R&S®NC router propagates to all networks that it is no longer available before the connection is terminated, thereby ensuring a quick change of routing priorities.
