INITIALIZATION

• Network Topology

             TN(Client1)

• Verification Points

  NUT's Message Format
  NUT will relay the Relay-reply message with DNS Recursive Name Server option and only relay 
  the DHCP-relay message(Reply) part of relay message option.
            

• Configuration

msg-type
          RELAY-REPL(13)

options
          Relay Message option
	  DHCP-relay-message = Reply w/with DNS Recursive Name Server option
