What is the default formula for calculating EIGRP composite metric? b) If K2, K4, K5, used in the default formula is 0, what is the formula used for calculating EIGRP composite metric? c) What is the metric for the path From R2 to R3 then 192.168.1.0/24 network? From R1 to R3 then 192.168.1.0/24 network? From R1 to R2, to R3 then 192.168.1.0/24 network? You have to show all your calculation steps. d) R1 can reach R3 192.168.1.0/24 directly or via R2. Which route will STP choose? Why? e) Explain why R2 is a feasibleot a feasible successor of R1 to R3 route in d). f) Explain why we always calculate the EIGRP metric from a router to the destination, not from a source to the destination
