Docker by default is the Linux with the Network Bridge implementation, in fact, the Openvswitch project as a mature virtual switch implementation, with a richer function. Personally, the future Docker will necessarily support Openvswitch as its default network bridge implementation. Interested students welcome the following steps to the taste. Environment Test in the Ubuntu 14.04 system. The operation process also applies to Redhat/centos series systems, but few commands and configuration files
