I’m currently testing Arista Wifi and I have issues with getting the tunneling part to work.
I have setup a tunnel interface with vlan 203 and key 203.
The endpoint is a Cisco ASR 1001.
The SSID is set to tunneling mode, I chose that tunnel interface I just created and I can see the GRE packets going out to the ASR. I even see the DHCP DISCOVERs from my test client.
However then nothing happens :( I found a few guides online and the ASR is configured like this:
interface Tunnel68
mac-address 0000.5e00.0068
ip address
no ip redirects
tunnel source GigabitEthernet0/0/3
tunnel mode ethernet gre ipv4
tunnel key 203
tunnel vlan 203
ip dhcp pool test_eogre

Could someone provide a working configuration?

Okay, don‘t mind, I found it :)
Mixed up the VLAN settings for the tunnel interface in WiFi mgmt.
However this opens another question for me:
Is there any gateway I can use to bridge the tunneled data to a local VLAN in the datacentre?
Because this is my final goal.

Hi Saskia!

If I am reading your question correctly then we can absolutely help you with that. I’d like to ask you a couple more questions about your particular use case to make sure we get it right. Could you reach out to me at so we can coordinate a time to talk?

Thank You!

For future Readers,

There are several ways to have data move throughout your network with our WiFi Solutions, the two major ones are dropped locally on the network where the Access Point is, and the second is to use VxLAN to Tunnel that traffic back to a Tunnel Endpoint (VTEP). Arista’s Trident X3 Based switches (the 720p, 7050X3, 7300X3) can achieve this, and when combined with the rest of our Campus Solution can make the network behave the way described.

If you have questions, please reach out to Support or your local Sales Team, we’re always happy to help.

Hi Andrew,
unfortunately VxLAN won’t work for remote branch offices since the MTU size is usally limited there. :(
Kind regards,
