I have deployed that with tripleO, but now we are recabling and redeploying it. So once I have it running I can share my configs, just name which you want :)

I have. That's the Triple-O docs and they don't go through the normal .conf files to explain how it works outside of Triple-O. It has some ideas but no running configurations.

hi, have you checked:  https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/features/routed_spine_leaf_network.html ?
I am following this link. I only have one network, having different issues tho ;)

Hey Tom,

Adding the OpenStack discuss list as I think you got several replies from there as well.

Thanks,

Good day, 

I'm bringing up a thread from June about DHCP relay with neutron networks in Ironic, specifically using unicast relay. The Triple-O docs do not have the plain config/neutron config to show how a regular Ironic setup would use DHCP relay. 

The Neutron segments docs state that I must have a unique physical network name. If my Ironic controller has a single provisioning network with a single physical network name, doesn't this prevent my use of multiple segments? 

Further, the segments docs state this: "The operator must ensure that every compute host that is supposed to participate in a router provider network has direct connectivity to one of its segments." (section 3 at https://docs.openstack.org/neutron/pike/admin/config-routed-networks.html#prerequisites - current docs state the same thing)
This defeats the purpose of using DHCP relay, though, where the Ironic controller does *not* have direct connectivity to the remote segment. 

Here is a rough drawing - what is wrong with my thinking here? 
Remote server: 10.146.30.32/27 VLAN 2116<-----> Router with DHCP relay <------> Ironic controller, provisioning network: 10.146.29.192/26 VLAN 2115

Thank you, 
Tom King
