Hi Team,Julia,

@Julia Thank you for the response.
>>Additionally is this UEFI mode or Legacy BIOS mode?
We are using UEFI.

We tried introspection for two nodes from the undercloud node. Te following
is our observation:
1. Undercloud is assigning an IPV6 IP to the node.

The PXE boot Failed with the following error:
PXE-E99: Unexpected network error.

On further debuging this issue, We found that a container: ironic_pxe_tftp
is in unhealthy state. But this container should be running.
On checking the logs, we  found the following:
"
[root at undercloud-ete log]# podman logs 356715c49cd4

dnsmasq: bad command line options: try --help

dnsmasq: bad command line options: try --help

dnsmasq: bad command line options: try --help

"
We had previously raised this issue in 2022 as well:
https://lists.openstack.org/pipermail/openstack-discuss/2022-June/029062.html

For this a bug was raised which was fixed
https://bugs.launchpad.net/tripleo/+bug/1978892

We cross-verified, and the changes are present on our undercloud. But still
we are unable to start the ironic_pxe_tftp container.

Could you please help us with this?

Thanks and Regards
Kushagra Gupta
