系统环境:CentOS Linux
network environment: two IP addresses, 10.4.34.31 and 10.4.35.31, the Mask is 255.255.255.0,
这两个子网的网关地址分别是10.4.34.1和10.4.35.1。
1. Configure the IP address 10.4.34.31 for the NIC eth0, configure the IP address for the NIC Eth1 to the 10.4.35.31 profile:
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
2. 配置默认网关为任意一个。这个默认网关,决定了系统主动去使用网络时,使用的接口。
配置文件:
/etc/sysconfig/network
3. 编辑路由表
a、修改
/etc/iproute2/rt_tables
,添加内容:
252 net2
251 net3
b、修改
/etc/rc
.
local
,添加原路返回路由:
ip route flush table net2
ip route add default via 10.4.34.1 dev eth0 src 10.4.34.31 Table net2
ip rule add from 10.4.34.31 table net2
ip route flush table net3
ip route add default via 10.4.35.1 dev eth1 src 10.4.35.31 Table net3
