# GRE
|
|
|
|
OpenWiFi 2.0 supports Generic Routing Encapsulation as an available "tunnel" protocol type.
|
|
|
|
This makes it possible to configure GRE for multiple types of deployments as any interface may be encapsulated by the "tunnel" parameter.
|
|
|
|
For example, to send all content of a specific SSID over an GRE tunnel, the following configuration would apply.
|
|
|
|
```
|
|
"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. Optionally the GRE tunnel itself may also carry a VLAN encapsulated payload. In the above example a WAN presentation of VLAN interface 20 has GRE tunnel. Within the GRE tunnel on WAN interface of VLAN 20 is a GRE payload with VLAN 30 in the payload header.
