8. EIGRP – Traffic Engineering
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.
