Use case: Secondary networks for network isolation
You can use an secondary network in situations where network isolation is needed, including control plane and data plane separation. For example, you can configure an secondary interface if you want pods to access a network on the host and also communicate with devices deployed to the edge. These edge devices might be on an isolated operator network or are periodically disconnected.
Isolating network traffic is useful for the following performance and security reasons:
- Performance
-
You can send traffic on two different planes to manage the amount of traffic on each plane.
- Security
-
You can send sensitive traffic onto a network plane that is managed specifically for security considerations, and you can separate private data that must not be shared between tenants or customers.
