My guess: You're running OVN. You need neutron-dhcp-agent running as well. OVN disables it by default and OVN's integrated DHCP service does not support options for network booting. -Julia On Thu, Feb 3, 2022 at 9:06 AM Anirudh Gupta <anyrude10@gmail.com> wrote:
Hi Team
I am trying to Provision Bare Metal Node from my tripleo Overcloud. For this, while deploying the overcloud, I have followed the *"default flat" *network approach specified in the below link
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/15/...
Just to highlight the changes, I have defined the
*ironic-config.yaml*
parameter_defaults: ... ... IronicIPXEEnabled: true IronicInspectorSubnets: - ip_range: *172.23.3.100,172.23.3.150* IronicInspectorInterface: 'br-baremetal'
Also modified the file *~/templates/network-environment.yaml*
parameter_defaults: NeutronBridgeMappings: datacentre:br-ex,baremetal:br-baremetal NeutronFlatNetworks: datacentre,baremetal
With this I have Followed all the steps of creating br-baremetal bridge on controller, given in the link below:
https://access.redhat.com/documentation/en-us/red_hat_openstack_platform/15/...
- type: ovs_bridge name: br-baremetal use_dhcp: false members: - type: interface name: nic3
Post Deployment, I have also create a flat network on "datacentre" physical network and subnet having the range *172.23.3.200,172.23.3.240 *(as suggested subnet is same as of inspector and range is different) and the router
Also created a baremetal node and ran *"openstack baremetal node manage bm1", *the state of which was a success.
Observation:
On executing "openstack baremetal node *provide* bm1", the machine gets power on and ideally it should take an IP from ironic inspector range and PXE Boot. But nothing of this sort happens and we see an IP from neutron range " *172.23.3.239*" (attached the screenshot)

I have checked overcloud ironic inspector podman logs alongwith the tcpdump. In tcpdump, I can only see dhcp discover request on br-baremetal and nothing happens after that.
I have tried to explain my issue in detail, but I would be happy to share more details in case still required. Can someone please help in resolving my issue.
Regards Anirudh Gupta
