Frustrated with VPLS problem. VC up but no traffic is passing.

Hi ,

I have scenario that I built on INE SPV3 racks.

XR1 ----------R3
 | |
 | |
 | |
 | |
XR2------------R4 ------------Trunk ------- 3550
  | |
  | |
 R5--------------|
  |
Trunk
  |
ME3400

I created vlan 100 interface on Me3400 and 3550. cannot ping each other.

VCs are up LDP, everything is working except I cant see MAC address on XR1
using "show l2vpn forwarding location " command.

R4 and R5 config are identical. I posted XR1 and R5 config here and VC
verification output.

Any input is much appreciated

Here is XR1 config:
