大佬教程收集整理的这篇文章主要介绍了Linux,添加子接口，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
这是我的ifconfig：
eth0 Link encap:Ethernet HWaddr 00:50:56:BB:00:0B
inet addr:10.6.19.18 Bcast:10.255.255.255 Mask:255.255.255.0
inet6 addr: fe80::250:56ff:febb:b/64 Scope:Link

eth0:1 Link encap:Ethernet HWaddr 00:50:56:BB:00:0B
inet addr:192.168.2.210 Bcast:192.168.2.255 Mask:255.255.255.0
UP BroaDCAST RUNNING MULTICAST MTU:1500 Metric:1
以下是我尝试配置eth0：1的内容
ifconfig eth0:1 192.168.2.210/32 up ip route add 192.168.2.210/32 via 10.6.19.18
这是我的netstat -r输出：
192.168.2.210 devserv. 255.255.255.255 UGH 0 0 0 eth0 192.168.2.0 * 255.255.255.0 U 0 0 0 eth0 10.6.19.0 * 255.255.255.0 U 0 0 0 eth0 link-local * 255.255.0.0 U 0 0 0 eth0 default 10.6.19.1 0.0.0.0 UG 0 0 0 eth0
有什么想法吗？谢谢你的期待

(你可以缩写ip命令：ip address add可以一直缩短到ip aa,而ip address show可以缩短为ip a s.如果你没有指定第二个参数,show是默认动作,所以你可以输入ip a,如果你想真的很简洁.)
您无需为本地子网添加路由.
