Juniper MX80 - Switching Traffic Between VLANs

Hi all,

First thing first, apologize for any accidentally mistake like English explaintion, incorrect community category post...etc.

The attached file is the diagram of the connectivity.

We have one customer with two different sites, Site A and Site B. Both sites are having IPTV and need to run multicast and talk to each other over pure Layer 2. They have purchased layer 2 link from L2 Provider 01 and received two different VLANs - VLAN10 and VLAN20. There is QinQ in place between each L2 Providers.

So what is the feature/solution on Juniper MX80 to get both different sites to talk to each other over pure Layer 2? We would appreciate for any input/idea/sugestion/solution you may have.

Thanks
