1、3线3IP服务器接口IP地址(vlan接口)
em1.12 单联通：120.52.139.9 掩码：255.255.255.240 网关：120.52.139.1
em1.13 单电信：123.58.236.26 掩码：255.255.255.248 网关：123.58.236.25
em1.16 单移动：223.71.150.91 掩码： 255.255.255.248 网关：223.71.150.89
2、配置路由表标签
test@ubuntu:~$ cat /etc/iproute2/rt_tables
#
# reserved values
#
255 local
254 main
253 default
0 unspec
#(增加下面联通、电信、移动路由标签)
252 cnc
251 ct
250 yd
3、配置路由表及路由策略
sudo ip route add table cnc via 120.52.139.1 dev em1.12 src 120.52.139.9
sudo ip rule add from 120.52.139.9 table cnc
sudo ip route add table ct via 123.58.236.25 dev em1.13 src 123.58.236.26
sudo ip rule add from 123.58.236.26 table ct
sudo ip route add table yd via 223.71.150.89 dev em1.16 src 223.71.150.91
sudo ip rule add from 223.71.150.91 table yd
4、把路由表及路由策略写到开机自启动
test@ubuntu:~$ sudo cat /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
sudo ip route add table cnc via 120.52.139.1 dev em1.12 src 120.52.139.9
sudo ip rule add from 120.52.139.9 table cnc
sudo ip route add table ct via 123.58.236.25 dev em1.13 src 123.58.236.26
sudo ip rule add from 123.58.236.26 table ct
sudo ip route add table yd via 223.71.150.89 dev em1.16 src 223.71.150.91
sudo ip rule add from 223.71.150.91 table yd
