## What it is
Multus CNI is a CNI meta-plugin for Kubernetes that enables attaching multiple network interfaces to pods, creating multi-homed pods. It works by delegating to other CNI plugins and follows the Kubernetes Network Custom Resource Definition De-facto Standard for specifying additional interface configurations.

## Use cases
- attach multiple network interfaces to kubernetes pods
- create multi-homed pods with separate control plane and data plane networks
- run containerized VNFs in kubernetes
- add vlan or vxlan secondary networks to pods
- separate pod traffic across multiple networks
- chain multiple CNI plugins in kubernetes

## When to choose
- your pods need more than one network interface in kubernetes
- you need to isolate control plane and data plane traffic
- you are deploying NFV/VNF workloads on kubernetes
- you need to attach pods to secondary networks via other CNI plugins

## When to avoid
- your pods only need the default single pod network
- you are not running kubernetes or a CNI-compatible runtime
- you want a simple overlay network without multi-homing
