## Overview

The ptp plugin creates a point-to-point link between a container and the host by using a veth device.
One end of the veth pair is placed inside a container and the other end resides on the host.
The host-local IPAM plugin can be used to allocate an IP address to the container.
The traffic of the container interface will be routed through the interface of the host.

## Example network configuration

```
{
	"name": "mynet",
	"type": "ptp",
	"ipam": {
		"type": "host-local",
		"subnet": "10.1.1.0/24"
	},
	"dns": {
		"nameservers": [ "10.1.1.1", "8.8.8.8" ]
	}
}
```
