[j-nsp] Layer 2 circuit - Traffic not flowing between Cisco and Juniper with mismatched VLAN ID

I configured something similar (vpls instead vlan-ccc) with something like
this on Juniper:

Interfaces {
            ge-1/1/6 {
             unit 901 {
                    description "C-PE2 to S-CE2";
                    encapsulation vlan-vpls;
                    vlan-id 901;
                    input-vlan-map {
                        swap;
                        vlan-id 801;
                    }
                    output-vlan-map swap;
                }
            }
