VPLS - ASR1k - ME3800 no l2 tunnelling ?

Hi All

 I`m playing in the lab and I`m struggling with achieving a full L2 tunnel over VPLS between an ME3800-X and ASR1004.

 Ascii Diagram: 3560[1] - ME3800X -> MPLS <- ASR1004 - 3560[2]

 Essentially, I`m trying to l2 tunnel vtp/cdp/stp over a VPLS connection between the ME and ASR. LDP is Up, L2 VFI is Up, I can ping from vlan 1 on 3560[1] to vlan 1 on 3560[2] so the VPLS is essentially up.

 That's where the issues start:

 STP traffic is not being passed, both switches are root bridges.

 If I configure 3560[1] as VTP server, 3560[2] does not get any new vlans.
 If I configure 2560[2] as a VTP Server, 3560[1] DOES get new vlans.

 (so VTP tunnelling works from the ASR to the ME3800, but not vice versa)

 CDP wise, I see nothing from 3560[1] (expected as the ME is configured to tunnel all), but I see the ASR from 3560[2]

 Stumped ? has anyone done anything similar ? its only untagged traffic (CDP/VTP/STP) I`m seeing issues with - but that's essentially what I need 
 The issue looks to the ASR, if I connect both 3560's to ports within the service-instance on the ME3800-X CDP, etc works, but I can't find any command that IOS-XE will accept to do the l2 tunnelling on the ASR.

 Config references a single neighbour but in truth this would be multiple, this is just a lab.

 Config from the ME:

Cisco IOS Software, ME380x Software (ME380x-UNIVERSALK9-M), Version 15.2(2)S, RELEASE SOFTWARE (fc1) - Metro Agg and Scaled Metro Agg Licenses, Metro Eth


interface GigabitEthernet0/24
 Descr to 3560[1]
 switchport trunk allowed vlan none
 switchport mode trunk
 mtu 9216
 service instance 1 ethernet
  encapsulation untagged , dot1q 1-4094
  l2protocol tunnel
  bridge-domain 100
 !
end

 l2 vfi test1 manual
 vpn id 1
 bridge-domain 100
 neighbor 1.1.1.1 encapsulation mpls


interface Vlan100
 no ip address
 xconnect vfi test1



-- Config from the ASR:

Cisco IOS Software, IOS-XE Software (PPC_LINUX_IOSD-ADVENTERPRISEK9-M), Version 15.3(1)S, RELEASE SOFTWARE (fc4)


interface GigabitEthernet0/0/7
 Descr connected to 3560[2]
 no ip address
 negotiation auto
 cdp enable
 service instance 100 ethernet
  encapsulation untagged , dot1q 1-4094
  bridge-domain 100
 !

bridge-domain 100
(ASR accepts the member config but doesn't show it)

l2 vfi test1 manual
 vpn id 1
 bridge-domain 100
 neighbor 2.2.2.2 encapsulation mpls


 There is a command on the ASR l2 vfi to forward l2protocol, but this errors not with BPDU tunnel not supported.  Config guides especially from IOS-XE reference using l2vpn - but half of the commands on the guide, despite this being for the correct software don't exist.

 Any assistance appreciated, head broken :-/
