在上一节中，两个host上四个容器的网络信息如下，然后进行网络连通性测试，可见通vlan的容器即使分布在不同的host上也是可以通信的，不同vlan的容器不管在不在同一个host上都不能通信

配置路由器，使不同vlan的容器进行通信，在找一台ubuntu服务器
# 1、启用转发功能
[root@docker-machine ~]# sysctl -w net.ipv4.ip_forward=1
net.ipv4.ip_forward = 1
# 2、配置对应两个vlan的子接口，并配置网关ip
[root@docker-machine ~]# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
