Description of problem:
Baremetal nodes aren't able to reach out the metadata server


Version-Release number of selected component (if applicable):
OSP 16.2.4 OVN DVR, baremetal nodes are on tenant vlan network


How reproducible:
- deploy a baremetal node RHEL
- curl http://169.254.169.254
curl: (7) Failed to connect to 169.254.169.254 port 80: Connection refused

Actual results:
metadata agent is unreachable

Expected results:
metadata agent is reachable


Additional info:
ironic on overcloud needs dhcpagents to work. the CU is using vlan tenant network and the dhcp used it is from dhcp agents at controller side.
