There is no issue if the internal ips(non-floating ips) can be in the different vlans in that case no need of floating ips and it will serve my purpose as I need to assign data center reachable ips to the VMs either in form of floating or non-floating ips. > > cheers > Ritesh > > Regards Ankush > > On Sun, Apr 21, 2013 at 11:19 PM, Salvatore Orlando > <sorla...@nicira.com>wrote: > >> Hi Ankush, >> >> unfortunately I am not aware of the possibility of using an external dhcp >> server for quantum, neither in folsom or grizzly). >> Currently, the dnsmasq option appears to be the only available one. >> >> Salvatore >> >> >> On 16 April 2013 08:02, ankush grover <ankushcen...@gmail.com> wrote: >> >>> Hi Friends, >>> >>> I have recently installed and configured Openstack Folsom release >>> without quantum on 2-node(Controller & Compute Node) on Ubuntu 12.10.
