ถ้าใช้สำหรับเล่นเน็ตอย่างเดียว ก็สามารถ ใช้ default route ได้เลยโดยใช้คำสั่ง
ip route replace default equalize nexthop dev ppp101 weight 2 nexthop dev ppp102 weight 2 nexthop dev ppp103 weight 2 nexthop dev ppp104 weight 2
ได้เลยครับและต้องเพิ่ม Script สำหรับ checklink.sh และ 0route กรณีมีเส้นใดเส้นหนึ่งหลุดไป ก็ให้ทำการวิ่งเส้นที่เหลือแทน
/etc/init.d/checklink.sh
