Hello. I created two external networks using multiple l3 agents by referring to both http://docs.openstack.org/admin-guide-cloud/content/adv_cfg_l3_agent_multi_extnet.html and https://answers.launchpad.net/neutron/+question/236230, and it seems work fine... When I tried to ping from a qrouter, which connects with both an external network called "external1" and an internal network, to a vm where located in the internal network, however, the ping could not be sent successfully. The qrouter can ping to br-ex, and another qrouter which connects with the second external network named "external2" also can ping to br-ex-2. The problem is that status for connection between each qrouter and internal network has been "DOWN" instead of "ACTIVE"... Did anybody suffer from such problem and solve it? I'd appreciate any help and comments for solving it. Thanks in advance. Best regards Byeong-Gi KIM -------------- next part -------------- An HTML attachment was scrubbed...
