To configure an EPL Service using all UNI Traffic and pushing two VLAN towards the NNI port and reverse path with a pop two VLAN

Follow the configuration below in Your Product-1 for UNI to NNI scenario:
Your Product-1

Your Product# configure terminal
Your Product(config)# shutdown spanning-tree
Your Product(config)# interface xl-ethernet 0/1
Your Product(config-if)# no shutdown
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/2
Your Product(config-if)# no shutdown
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/1
Your Product(config-if)# bridge port-type customerEdgePort 
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/2
Your Product(config-if)# bridge port-type providerNetworkPort three-tagged
Your Product(config-if)# switchport egress ether-type 0x88a8
Your Product(config-if)# switchport egress inner-ether-type 0x8100
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# no interface vlan 1
Your Product(config)# end
Your Product# configure terminal
Your Product(config)# vlan 100
Your Product(config-vlan)# ports xl-ethernet 0/1 xl-ethernet 0/2 untagged gigabitethernet 0/1
Your Product(config-vlan)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/1
Your Product(config-if)# switchport customer-vlan 10 service-vlan 100
Your Product(config-if)# end
Your Product# configure terminal
Your Product(config)# interface xl-ethernet 0/2
Your Product(config-if)# switchport three-tagged-pnp tunnel vlan 1000
Your Product(config-if)# switchport three-tagged-pnp tunnel ethertype 0x9100
Your Product(config-if)# switchport three-tagged-pnp tunnel priority 7
Your Product(config-if)# switchport three-tagged-pnp tunnel use-dei true
Your Product(config-if)# end

Check EtherType status:

show three-tagged-pnp vlan config

Sample output:

Your Product# show three-tagged-pnp vlan config
Switch default
