一、ip route显示和设定路由
1、显示路由表
[root@centos7 ~]# ip route show
default via 192.168.150.254 dev enp0s3 proto static metric 1024
192.168.150.0/24 dev enp0s3 proto kernel scope link src 192.168.150.110
太难看了，格式化一下(显示的是默认网关和局域网路由，两行的内容没有共通性)：
[root@centos7 tmp]# ip route show|column -t
default via 192.168.150.254 dev enp0s3 proto static metric 1024
192.168.150.0/24 dev enp0s3 proto kernel scope link src 192.168.150.110
2、添加静态路由
[root@centos7 ~]# ip route add 10.15.150.0/24 via 192.168.150.253 dev enp0s3
[root@centos7 ~]#
[root@centos7 ~]# ip route show|column -t
default via 192.168.150.254 dev enp0s3 proto static metric 1024
10.15.150.0/24 via 192.168.150.253 dev enp0s3 proto static m
