<p class="MsoNormal">But I haven’t understood why it is certral oam interface rather than mgmt interface to access registry.central. This guide[1] says the mgmt interface is okay to bootstrap in the section "install a subcloud" step 5. So if the registry.local
can be accessed by mgmt network, wo don’t have to access the OAMs between central and subcloud. In addition, there is may only one interface that could be connected between central and subcloud in some case, and how to handle these cases with distributed cloud?<o:p></o:p></p>
