Hi

I setup a two node openstack env. The topology is like below

http://docs.openstack.org/mitaka/install-guide-rdo/_images/network2-connectivity.png (图像描述)

The gateway is 10.0.0.1 on Router Namespace qg. The vm is on Compute Node called Provider instance. The ip is 10.0.0.8.

I am trying to ping 10.0.0.1 from 10.0.0.8 but it not succeed.

I capture some package on interface2 at controller and compute. Find the ARP req and reply can be seen on controller node interface2. But arp reply can not get interface2 at compute node.

Do you have any suggestion please?

This is famous question I think. I hit the same problem. I did not find good way to fix, but share some hints

  1. Do you install Openstack on VM? If not, then check security group, mac filter, also check if can ping by use ip netns

  2. If yes, check iptables
