What Are the Differences Between the Primary and Extension NICs of BMSs?

What Are the Differences Between the Primary and Extension NICs of BMSs?
They are different in the following ways:
- Generally, the OS default routes preferentially use the primary NICs. If the OS default routes use the extension NICs, network communication will be interrupted. Then, you can check the route configuration to rectify the network communication error.
- By default, only the primary NICs can communicate with the public service zone (zone where PaaS and DNS services are deployed). The extension NICs cannot communicate this zone.
