In calico, how does Host A connect to docker on Host B?

  docker, question

I deployed mesos and marathon, used consul for service discovery, and then used calico to assign a separate IP to each docker. However, after IP assignment is completed, the Dockers across hosts can be connected, but it is not possible to ping Dockers above Host B from Host A? How should this be achieved so that host A can connect with the docker on host B to completely connect the docker with the host

Has the landlord solved it yet?
