Multiple interfaces
To reduce the likelihood of guest traffic impacting management traffic, segregation of traffic between multiple physical interfaces is recommended. At a minimum, two interfaces should be used: one that serves as a dedicated interface for management and API traffic (control plane), and another that serves as a dedicated interface for external and guest traffic (data plane). Additional interfaces can be used to further segregate traffic, such as storage.
