Hello,
I am running a spine-leaf architecture within a residential estate to carry FTTH traffic between the internet service providers and their end-users. I am using the QFX5100-48S device for both the spine and leaf and running Junos version 17.3R3-S4. I have deployed EVPN-VXLAN as the overlay to deliver the services between the different end-points. I have successfully deployed services (single tag and double tag) between different leaf devices at different locations but the issue I am experiencing is as follows:
I have an ISP whose NNI (ingress) and the FTTH OLT NNI (egress) terminate on the same leaf device. Both the ports have been configured as q-in-q with the packet flow ISP (any c-vlan) -> Leaf-1 ge-0/0/3 (encapsulate c-vlan in s-vlan) -> Leaf-1 xe-0/0/0 (maintain s-vlan and c-vlan) -> FTTH OLT -> End-User. Both the ports are configured within the same VLAN and VNI.
I am learning the mac addresses of the connected devices on each port but they are unable to send traffic between. The config being used is below.
set interfaces xe-0/0/0 flexible-vlan-tagging
set interfaces xe-0/0/0 encapsulation extended-vlan-bridge
set interfaces xe-0/0/0 unit 3333 vlan-id 3333

Any assistance or advice would greatly appreciated. Thanks.
