Re: [Openstack] can two tenants create two identical network?
I am assuming you are using Quantum for networking, in which case make sure you have enable overlapping IPs by setting: allow_overlapping_ips = True in /etc/quantum/quantum.conf You also need to enable namespaces: use_namespaces = True in /etc/quantum/l3_agent.ini Regards Balu On Fri, May 17, 2013 at 3:22 PM, Liu Wenmao marvel...@gmail.com wrote: Hi Suppose there are two tenants: A and B, they can create their own networks, but the networks are both 100.0.0.0/24, I think it is possible in multi-tenant scenarios since networks of different tenants are isolated, But in openstack, I have a network creation error, which says there is an existing network already.

In addition to the below changes set use_namespaces=False in dhcp_agent.ini too.Make sure that your operating system supports network namespaces Sent from my iPhone On 17-May-2013, at 3:32 PM, Balamurugan V G balamuruga...@gmail.com wrote: I am assuming you are using Quantum for networking, in which case make sure you have enable overlapping IPs by setting: allow_overlapping_ips = True in /etc/quantum/quantum.conf You also need to enable namespaces: use_namespaces = True in /etc/quantum/l3_agent.ini Regards Balu On Fri, May 17, 2013 at 3:22 PM, Liu Wenmao marvel...@gmail.com wrote: Hi Suppose there are two tenants: A and B, they can create their own networks, but the networks are both 100.0.0.0/24, I think it is possible in multi-tenant scenarios since networks of different tenants are isolated, But in openstack, I have a network creation error, which says there is an existing network already.

Re: [Openstack] can two tenants create two identical network?
Yes, I use namespace and quantum. After I set the allow_overlapping_ips option, it works, thanks guys. To Kumaran: Do you mean that namespace support should be disabled in DHCP agent, but why? If I disable namespace in dhcp_agent.ini, is it possible that something does not work?

Liu. Sorry I meant to enable namespaces as true . Mistakenly I mentioned as false . It's good that you made it worked now Sent from my iPhone On 17-May-2013, at 10:18 PM, Liu Wenmao marvel...@gmail.com wrote: Yes, I use namespace and quantum.
