VyOS utilizes VPP (Vector Packet Processor) to provide high-performance data
plane processing. While physical interfaces are typically managed through the
Linux kernel using ``linux-cp`` (Linux Control Plane) integration, VyOS also
supports creating dedicated VPP interfaces for enhanced flexibility and
performance.

Why VPP Interfaces?
-------------------

VPP interfaces offer several advantages:

* **Total Isolation**: VPP interfaces operate entirely within the VPP data
  plane, providing isolation from the Linux kernel when needed.
* **Advanced Features**: Access to VPP-specific functionality not available
  in standard Linux interfaces.
* **Flexible Deployment**: Some interface types are only available as VPP
  interfaces or may not be supported by the kernel.
* **Specific scenarios**: Not all use cases require integration with the
  Linux Kernel.

Integration with Kernel
^^^^^^^^^^^^^^^^^^^^^^^

VyOS provides seamless integration between VPP and kernel networking.
This allows you to leverage the strengths of both approaches:
create interfaces inside VPP, and access them from the Linux kernel and other
services.
