MultiPath :: 同時使用兩個以上ADSL
												
																											環境: 
Linux(FC3) with eth0, eth1, eth2 
local area 
eth0: 192.168.10.254/24 
ADSL 512k/8M 
eth1: 111. 111.111.1/24 gw 111.111.111.254 
FTTB 2M/2M 
eth2: 222.222.222.142/28 gw 222.222.222.129 
在rc.local裡面加一個 mpath.sh 
== cut start == 
#!/bin/sh 
ip rule add pref 10 to 192.168.10.0/24 table 10 
ip route add 192.168.10.0/24 table 10 dev eth0 
ip rule add pref 20 from 111.111.111.1 table 20 
ip route add default table 20 via 111.111.111.254 
ip rule add pref 30 from 222.222.222.142 table 30 
ip route add default table 30 via 222.222.222.129 
ip route show 
ip route flush cache 
== cut end ==
