So docker is running like ```docker -d -b=br0```\r\n\r\nThe subnets I have tried are below:\r\n\r\n_10.0.0.1/24_\r\n_10.1.10.1/24_\r\n_172.16.0.1/24_ \r\n\r\nThere is nothing special in my configuration my forward delay is 1 on the bridge (I used to set 9).\r\n\r\n* Switches Involved.\r\n + Cisco SG-300 24 port\r\n - Cisco SG-200 24 port\r\n\r\nRapid STP is enabled so basically what happens is it flaps the ip between the ports assuming it.  This makes it impossible to docker build on 2 servers at once (apt-get update usually fails)\r\n\r\nI don't care what IP is given out; I just don't want it to give out an IP already in use.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/docker/docker/issues/comments/69979147","html_url":"https://github.com/docker/docker/issues/6561#issuecomment-69979147","issue_url":"https://api.github.com/repos/docker/docker/issues/6561","id":69979147,"user":{"login":"jfrazelle","id":1445228,"avatar_url":"https://avatars.githubusercontent.com/u/1445228?v=3","gravatar_id":"","url":"https://api.github.com/users/jfrazelle","html_url":"https://github.com/jfrazelle","followers_url":"https://api.github.com/users/jfrazelle/followers","following_url":"https://api.github.com/users/jfrazelle/following{/other_user}","gists_url":"https://api.github.com/users/jfrazelle/gists{/gist_id}","starred_url":"https://api.github.com/users/jfrazelle/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jfrazelle/subscriptions","organizations_url":"https://api.github.com/users/jfrazelle/orgs","repos_url":"https://api.github.com/users/jfrazelle/repos","events_url":"https://api.github.com/users/jfrazelle/events{/privacy}","received_events_url":"https://api.github.com/users/jfrazelle/received_events","type":"User","site_admin":false},"created_at":"2015-01-14T19:49:16Z","updated_at":"2015-01-14T19:49:16Z","body":"sorry about that it is hard to tell sometimes.
