We have a spec for implementing a DHCP relay agent , which would enable this. We have implemented this, but it's not upstream (yet!). You would have to download our adapter  and dissect it to get the code from there, which may be pretty painful, because the package includes lots of changes related to our integration rather than just the relay.
The adapter uses ISC dhcrelay, but we had to patch it to add the link selection option. That code is also included with the adapter package, along with a build script for it.  https://blueprints.launchpad.net/neutron/+spec/dhcp-relay  https://www.infoblox.com/products/private-hybrid-cloud/openstack-adapter From: Erhan Ekici <erhan.ek...@gmail.com<mailto:erhan.ek...@gmail.com>> Reply-To: "OpenStack Development Mailing List (not for usage questions)" <email@example.com<mailto:firstname.lastname@example.org>> Date: Tuesday, January 6, 2015 at 9:00 AM To: foss geek <thefossg...@gmail.com<mailto:thefossg...@gmail.com>> Cc: "OpenStack Development Mailing List (not for usage questions)" <email@example.com<mailto:firstname.lastname@example.org>>, openstack <openst...@lists.openstack.org<mailto:openst...@lists.openstack.org>> Subject: Re: [openstack-dev] [Openstack] [Devstack][Neutron]Neutron with External DHCP server Hi, As far as I know, there is a spec and feature for external dhcp server configuration but just for ironic project (bare metal installation). Btw, I have not tested it yet. http://specs.openstack.org/openstack/ironic-specs/specs/juno/support-external-dhcp.html Erhan, On Tue, Jan 6, 2015 at 1:04 PM, foss geek <thefossg...@gmail.com<mailto:thefossg...@gmail.com>> wrote: Dear All, Is it possible to configure neutron to take VM ip from external DHCP server?
