Re: How to use existing DHCP for giving floating IPs in Openstack
For floating ip you need to define a pool of ip that your machine would
get. You can use auto_assign floating ip to assing a FIP from the pool
automatically as the machine gets provisioned.
Or you can use flat network-manager for nova network and use your existing
dhcp server to provide ip's to your instance in openstack(in that case your
machine directly gets a data-centre reachable ip or the ip you want to
assign as floating ip but In that case Vlans can not be used.
Hope that helps you
