QinQ Topology not Working

Hello to everyone,
I am trying to test the QinQ topology with the attached visual.
I thought it would work with a simple one line configuration, but I didn't succeed.

I am testing topology on Nexus9k on EVE-NG. Can you tell me where I went wrong?

Device configuration is available in the attachment.

When I open wireshark from the right side pc by pinging from the left side pc, I see that there is no package.

Firewalls are turned off on computers.

 

C:\Users\LAB>ping 10.10.10.2

10.10.10.2 with 32 bytes of data:
10.10.10.1 cevabı: Destination host unreachable.
10.10.10.1 cevabı: Destination host unreachable.
10.10.10.1 cevabı: Destination host unreachable.
10.10.10.1 cevabı: Destination host unreachable.

Ping statistics for 10.10.10.2;
Package: Outgoing = 4, Incoming = 4, Lost = 0 (% 0 lost),

 

Thank you..

Hello,

 

I think the ports connecting the customer switches to the provider switches need to be access ports in Vlan 10:

 

Configure the below on both of your customer switches:

 

interface Ethernet1/2
description *** to_PROVIDER ***
switchport mode access

switchport access vlan 10
mtu 9216

Thank you for the answer. As you said, I changed it to "access", but I could not access it.
