Hi, Matt and all,

I met an strange issue when deploying an IPv6 duplex system. I need your help to check if anything I missed during the deployment.

I setup a container to run NAT64/DNS64 gateway on my test machine and 2 vms for a duplex system.

Except the gateway and the localhost.yml I followed everything as a normal ipv4 duplex system setup.

The controller-0 was unlocked and controller-1 can be installed via PXE, but when controller-1 finished installing and rebooted for the first time, mgmt network can only get the  PXE IP from DHCP server. Attached /var/log/anaconda/journal.log.

If I config the mgmt network on controller-1 with ipv6 IP manually, it can ping to controller-0 successfully.

Is there any special thing I need to do for a IPv6 setup?

And here’s my localhost.yml:

---

system_mode: duplex

management_subnet: fd01::/96

management_start_address: fd01::2

management_end_address: fd01::50

management_multicast_subnet: ff08::1:1:0/124

cluster_host_subnet: fd02::/96

cluster_pod_subnet: fd03::/96

cluster_service_subnet: fd04::/112

external_oam_subnet: fd00::/96

external_oam_gateway_address: fd00::1

external_oam_floating_address: fd00::2

external_oam_node_0_address: fd00::3

external_oam_node_1_address: fd00::4

admin_username: admin

admin_password: Local.123

dns_servers:

  - fd00::1

Thanks!
