[ipv6-wg] Request to verify ipv6 addressing scheme in my diagram

Hi Team, I have created a small IPv6 based corporate network diagram and want an expert to validate if the addressing scheme used is fine or not. I am attaching the diagram where I have created the network. Can you please assist me with validation of the address scheme and the network. If need be, I can speak to you on telephone or Skype too. But request you to help me by checking the diagram. Thanks Maninder Singh
