ubuntu 14.04配置3线3IP

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 class="lazy" data-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 class="lazy" data-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 class="lazy" data-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 class="lazy" data-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 class="lazy" data-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 class="lazy" data-src  223.71.150.91

sudo ip rule add from  223.71.150.91 table yd
