Hello.

I have a lab test scenario that the original purpose is about to bridging the q-in-q at double vlans through VXLAN. I have two topologies that will have to show you.

## --- First topology. ---

Basically we have 2 QFX5120s as leaf switches, 1 QFX5200 as spine, and 1 MX240 that will have 2 virtual routers for serving the endpoints.

MX240[VR1] ge-2/1/4.200 <---> ge-0/0/0.200 QFX5120  et-0/0/48.0<---> et-0/0/5.0 QFX5200 et-0/0/2.0 <---> et-0/0/48.0 QFX5120 ge-0/0/0.200 <---> ge-2/1/3.200  MX240[VR2]

Let's jump for VXLAN's complications, there is no problem.  Go to endpoints and leaf switches. This will be my configuration for MX240 and QFX5120 for taking bridge for dual tag VLANs.

## MX240 configurations.
{master:member0-re0}
xxx@MX240_LAB_CE2> show configuration interfaces ge-2/1/3  
description CE2;
flexible-vlan-tagging;
mtu 9216;
encapsulation flexible-ethernet-services;
unit 209 {
    vlan-tags outer 200 inner 20;
    family inet {
        address 10.0.1.0/31;
    }
}

{master:member0-re0}
xxx@MX240_LAB_CE2> show configuration interfaces ge-2/1/4    
description CE1;

unit 200 {
    vlan-tags outer 200 inner 20;
    family inet {
        address 10.0.1.1/31;
    }
}

{master:member0-re0}
xxx@MX240_LAB_CE2> show configuration routing-instances 
CE2 {
    instance-type virtual-router;
    interface ge-2/1/3.200;
}
CE3 {
    instance-type virtual-router;
    interface ge-2/1/4.200;
}

## QFX5120 configurations.

{master:0}
xxx@QFX5120-48Y-LEAF-A1> show configuration interfaces ge-0/0/0 
description to.ce2;
flexible-vlan-tagging;
mtu 9216;
unit 200 {
    family ethernet-switching {
        interface-mode trunk;
        vlan {
            members vn200;
        }
    }
}

{master:0}
xxx@QFX5120-48Y-LEAF-A1> show configuration routing-instances evpn-1 
instance-type mac-vrf;
....
vlans {
    vn200 {
        description VLAN200;
        vlan-id 200;
        vxlan {
            vni 10012;
            encapsulate-inner-vlan;
        }
    }
}

xxx@QFX5120-48Y-LEAF-A1> show configuration protocols l2-learning 
decapsulate-accept-inner-vlan;
telemetry {
    enable-remote-entries;
}

And another QFX5120 with the same pattern configuration.

It did success carry my ping test to another virtual router of my MX240. With the test would be S-VLAN in 200 and C-VLAN 20. The leaf switches is able to carry on S-VLAN 200. Then my next topology.

## --- Second topology ---

Now we have 1 QFX5120 as leaf switch, 1 ACX7100 as leaf switch, 1 QFX5200 as spine, 1 MX240 with 1 virtual router, 1 QFX5120 as serving endpoint.

QFX5120  et-0/0/5.200<---> et-0/0/4.200  ACX7100  et-0/0/48.0 <---> et-0/0/0.0 QFX5200 et-0/0/2.0 <---> et-0/0/48.0 QFX5120 ge-0/0/0.200 <---> ge-2/1/3.200  MX240[VR2]

Basically we just copy the same configuration. The ACX7100 has a problem when try to bridge dual tags from it's endpoint from QFX5120.

##QFX5120 configurations.

    family inet {
        address 10.0.1.0/31;
    }
}

Still receiving the MAC address from QFX5120 leaf switches, but ACX7100 doesn't catch the MAC address from QFX5120 endpoint at this time. So my basic question is, just how to make ACX7100 is accepting the dual VLAN tags for bridging them likewise of QinQ? We did take test for one vlan tag, and it did sucess. Is there any missing on the configuration on ACX7100? I did suspect of missing configuration at the interface,

Need some clues. :)

I also having the output on both ACX7100 and QFX5120.

I noticed that ACX7100 doesn't make the same output just like QFX5120. QFX5120 is quite simple which it is transparently accept everyting. But in ACX7100 has VLAN Tag 0x0000.0. It should has en effect on it. And on the next, Ethernet-Bridge DF. What is DF at this point?
