Added to routing table when variance is 3?R1 50 30 yes yes yes yesR2 90 40 no yes yesR3 120 60 No No No NoBefore considering the variance, note that in this example, the route through R1 is a successor route because it has the lowest metric value. This also means that the route through R1 has a metric (50) of FD. The route through R2 is an FS route because its RD is 40,which is less than FD (50). The route through R3 is not an FS route because its RD is 60,which is greater than FD (50).In the default configuration, the variance is 1,the metric must be exactly equal to be considered equal, so only the successor routes are added to the routing table.If the variance2 command is configured, FD(50) is multiplied by variance(2), resulting in 100. the metric of the route through R2 is 90, which is less than the variance xFD=100, so R4 will also add the route through R2 to the routing table. This router can then implement the two routes on the219 Chapter 10 Implementing IPv4 EIGRPtraffic load balancing. The third route has a metric of 120,which is greater than the variance xFD=100,so it is not added to the routing table.If the variance3 command is configured, the result of multiplying FD(50) by 3 is 150, and the calculated metric value for all three routes is less than 150. however, the route through R3 is not an FS route, so it cannot be added to the routing table because of the possibility of causing routing loops. The following list summarizes the key points about variance. ,fuchs... The variance is multiplied by the current FD (the metric of the best route to the subnet). Fouche. Assuming that the maximum path setting allows more routes. any FS routes whose calculated metric is less than or equal to the result of multiplying the variance by the FD are added to the IP routing table.
