Hi Team, we have installed Undercloud with Train release on Centos8 using ipv6 as loca_ip in undercloud.conf file. Undercloud seems to be installed successfully and we are able to see IPv6 endpoints as well. Also, the OpenStack overcloud images are uploaded and well visible on http://<ipv6>:8088 tftp link. Problem Statement: During introspection start, we see that ipv6 is allocated to the node, further no action is being performed. Please refer the screen attached. [image: image.png] As we can see ipv6 bbbb:bbbb:bbbb::9 is allocated to the desired machine. Furthermore, we see that the link is shown as down for the same mac, which also becomes up as can be seen but the configuring on that NIC eventually fails for some reason. Any idea/inputs on this please? -- ~ Lokendra
