Open Stack

Thanks for your inputs. We will consider the below details while designing
our network. Our second option is to use L3 Agents with HA for routing.In
this approach, Currently most of the large openstack deployers are using
their own customized code for network segments. But we are planning to
segment/cluster/group our network nodes by assigning network node to
availability zones.  Did anyone used this approach in large /medium scale
deployments. Please let us know if you have any  suggestions or inputs on
this approach.
