# GRE

OpenWiFi 2.0 supports Generic Routing Encapsulation as an available "tunnel" protocol type.&#x20;

This makes it possible to configure GRE for multiple types of deployments as any interface may be encapsulated by the "tunnel" parameter.&#x20;

For example, to send all content of a specific SSID over an GRE tunnel, the following configuration would apply.&#x20;

```
	"interfaces": [
		{
			"name": "WAN",
			"role": "upstream",
			"ethernet": [
				{
					"select-ports": [
						"WAN*"
					]
				}
			],
			"ipv4": {
				"addressing": "dynamic"
			}
		},
		{
			"name": "GRE",
			"role": "upstream",
			"vlan": {
				"id": 20
			},
			"tunnel": {
				"proto": "gre",
				"peer-address": "far end IP address"
			},
			"ssids": [
				{
					"name": "Tunneled SSID via GRE from VLAN 20 Interface",
					"wifi-bands": [
						"2G", "5G"
					],
					"bss-mode": "ap",
					"encryption": {
						"proto": "none",
						"ieee80211w": "optional"
					},
					"rate-limit": {
						"ingress-rate": 100,
						"egress-rate": 100
					},                    
					"roaming": {
						"message-exchange": "ds",
						"generate-psk": true
					}
                }
			]
		},	
```

In the above example, the WAN untagged port will request DHCP in addition to present a VLAN interface with id 20 that both initiates the GRE tunnel as well as passes SSID traffic over that tunnel.
