Kondisi normal tentunya trafik dari router R1 menuju Loopback R3 adalah langsung menuju router R3 karena perhitungan bandwitdhnya. nah bila diinginkan trafik melewati router R2 dulu maka parameter metric bisa kita rubah agar memenuhi hal tersebut, salah satunya adalah Delay. ================================================================ Kondisi awal.......

Perhatikan nilai metric nya..... untuk mencari nilai varience yang akan kita masukkan, maka 2739200 dibagi 435200 = 6,29 maka nilai varience yang diset adalah 7 (pembulatan harus keatas utk nilai berapapun) R1(config)#router eigrp 10 R1(config-router)#variance 7
