konfigurasi router mikrotik versi 3.10

konfigurasi load balance dan failover mengacu pada :
http://wiki.mikrotik.com/wiki/ECMP_Failover_Script

karena paling praktis dan masuk akal bahwa selain traffic http sangat riskan jika harus berpindah-pindah gateway.

berikut adalah hasil export dari konfigurasi router mikrotik versi 3.10 yang digunakan

semoga script-script diatas bisa langsung di import tinggal disesuaikan saja ip-ip nya

kelemahan dari konfigurasi ini adalah ip 10.168.2.1 walaupun ADSL nya down tetap bisa diping karena itu ip dibelakang adsl-router harusnya 10.168.2.1 dibagian script diganti dengan ip statik ADSL , jadi kalau ADSL nya mati mestinya ip tersebut tidak bisa di ping.
