三、CentOS7-a主机下添加路由

###查看当前主机ip 信息 [root@centos7-a ~]# ip addr list 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eno16777728: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 00:0c:29:57:26:9d brd ff:ff:ff:ff:ff:ff inet 172.24.8.131/24 brd 172.24.8.255 scope global dynamic eno16777728 valid_lft 1088sec preferred_lft 1088sec inet6 fe80::20c:29ff:fe57:269d/64 scope link valid_lft forever preferred_lft forever ###查看当前主机路由信息 [root@centos7-a ~]# ip route list 172.24.8.0/24 dev eno16777728 proto kernel scope link src 172.24.8.131 metric 100 [root@centos7-a ~]# # Author : Leshami [root@centos7-a ~]# # Blog : http://blog.csdn.net/leshami [root@centos7-a ~]# ip route add default via 172.24.8.254 [root@centos7-a ~]# ip route list default via 172.24.8.254 dev eno16777728 172.24.8.0/24 dev eno16777728 proto kernel scope link src 172.24.8.131 metric 100 ###测试到虚拟路由器网关ip连通性 [root@centos7-a ~]# ping 172.24.8.254 -c 2 PING 172.24.8.254 (172.24.8.254) 56(84) bytes of data. 64 bytes from 172.24.8.254: icmp_seq=1 ttl=64 time=0.268 ms 64 bytes from 172.24.8.254: icmp_seq=2 ttl=64 time=0.302 ms --- 172.24.8.254 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms rtt min/avg/max/mdev = 0.268/0.285/0.302/0.017 ms ###测试到虚拟路由器ip连通性 [root@centos7-a ~]# ping 192.168.1.175 -c 2 PING 192.168.1.175 (192.168.1.175) 56(84) bytes of data. 64 bytes from 192.168.1.175: icmp_seq=1 ttl=64 time=0.475 ms 64 bytes from 192.168.1.175: icmp_seq=2 ttl=64 time=0.443 ms --- 192.168.1.175 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1000ms rtt min/avg/max/mdev = 0.443/0.459/0.475/0.016 ms

四、Windows 10下配置路由
