Did you get a chance to look at the configuration which I have sent in
my earlier email?
Are there any gaps?

Waris,

The attachment circuit is already configured as per the start of the
thread.

es-103-glsfb#sh vfi
Legend: RT=Route-target, S=Split-horizon, Y=Yes, N=No

VFI name: ME002555, state: up, type: multipoint signaling: LDP
  VPN ID: 116, VPLS-ID: 9930:116
  RD: 9930:116, RT: 9930:116
  Bridge-Domain 116 attachment circuits:
    Vlan116
  Neighbors connected via pseudowires:
