Hi,

The provisioning network needs to be isolated, typically by using VLANs on the switch: https://docs.openstack.org/project-deploy-guide/tripleo-docs/latest/environments/baremetal.html#networking

In general, you can only have one DHCP server on an L2 network (ignoring high-availability DHCP setups).

Thanks,

Ollie

Hi all,

I have a situation, when in my network, I have loads of equipment, which I do not control. and Inspection range gets occupied quite fast.

and in TCP dump I get such messages:
DHCP-Message Option 53, length 1: NACK
Server-ID Option 54, length 4: DHCPD-IP
MSG Option 56, length 21: "address not available"

I have disabled: enabled_node_discovery = false

Anything else?

maybe additional environment options for undercloud I could provide?

Than kyou in advance, have a good $day_time
