Thanks very much for the reply, but I don't understand mpls enough yet for your post to help me with my specific scenario. I should have posted more info. Here's the actual topology and configs that's currently not working. It will be obvious by the mistakes in the configs that I don't understand MPLS yet, but maybe this gives a better idea of what we are trying to accomplish and what needs correcting in my configs to make it work. Thanks.

Thanks for the additional info.
I will look at this carefully and reply when the opportunity arises. I assume you are running the ME3800X models with 15.1 or higher code and the advanced services with allows full mpls configurations.
I will also assume your IGP (OSPF) is configured correctly as well.
Chat with you soon

attached ASR9K Config Sheet
No need to make any changes. I will write a config and post it soon.
The config I wrote was for point to point pseudowire/EFP. You are attempting VPLS so the config changes somewhat.
Please read this documentation,
Look for section;
EFPs and Ethernet over Multiprotocol Layer Switching (EoMPLS)
Enabling EoMPLS
This section includes this information about configuring EoMPLS on a switch used as a provider-edge router:
•
EoMPLS Configuration Guidelines
•Configuring the Pseudowire Using Pseudowire Class
•Configuring L2VPN Interworking
•Packet Flow in an EoMPLS Network
•Configuring L2VPN Pseudowire Redundancy
I particularly like the EVC XConnection configuration because you have the option of creating VLan based service instances without globally defining the VLan itself. I understand the 3800x has Asics for bridge-domain processing, not done with software like the 7600 router.
Also when encapsulating with MPLS the ASR9Ks are only label swapping. No additional VLan based configuration required.
This option also gives you the ability to create traffic engineering from 3800x to 3800x. Primary, secondary, and tertiary using FRR. Or you cant just let the IGP to take care of LSP dynamically.
I understand the 3800x has Asics for bridge-domain processing, not done with software, however you have to globally define the vlan you are bridging.
I hope this helps you.
