Mikrotik DUAL WAN Load Balancing using PCC method

Pada pembahasan sebelumnya Load Balancing Dual WAN dengan menggunakan Mikrotik 3.0 maka di kesempatan ini Pakirwan mencoba memposting Load Balancing Mikrotik dengan menggunakan RB750 yang memiliki 5 port router. PCC disini maksudnya per-connection-classifier

yang terdapat pada RB750 dengan asumsi sebagai berikut:

2 port yang terhubung dengan dua Router DSL yang berbeda,

dan 1 port terhubung dengan LAN.

Kedua DSL memiliki kecepatan yang sama.

Local = 192.168.0.1

Modem1 = 192.168.1.1

Modem2 = 192.168.2.1

Jangan lupa untuk merubah nama-nama dari setiap interface nya.

Berikut ini adalah script yang Sobat bisa kopi paste kan diterminal mikrotiknya.
