Ruslanas, that would be excellent! I will reply to you directly for details later unless the maillist would like the full thread. Some preliminary questions: - Do you have a separate physical interface for the segment(s) used for your remote subnets? The docs state each segment must have a unique physical network name, which suggests a separate physical interface for each segment unless I'm misunderstanding something. - Are your provisioning segments all on the same Neutron network? - Are you using tagged switchports or access switchports to your Ironic server(s)?

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... ? 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#pr... - 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
