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/environm... In general, you can only have one DHCP server on an L2 network (ignoring high-availability DHCP setups). Thanks, Ollie On Fri, 4 Dec 2020 at 19:34, Ruslanas Gžibovskis <ruslanas@lpic.lt> wrote:
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?
