INITIALIZATION

• Network Topology

          TN(Relay agent1)  
             |
Link0 -------+-----------+--------------- 3ffe:501:ffff:100::/64
                         |
                       NUT(Server1)
  

• Verification Points

          

Relay-reply Message Format
      
msg-type
          RELAY-REPL(13)
      
Interface-Id option
	  Same as the RELAY-FORW Message
          
Interface-Id option's format
option-code
OPTION_INTERFACE_ID (18)
option-len
Length of interface-id field.
interface-id
An opaque value of arbitrary length generated
by the relay agent to identify one of the
relay agent's interfaces.

• Configuration

Device Name	Device Type	I/F	Assigned Prefix	Link Local Addr	MAC Addr
Server1	NUT	Link0	3ffe:501:ffff:100::/64	NUT's Linklocal address	NUT's MAC address
Relay agent 1	TN	Link0	3ffe:501:ffff:100::/64	fe80::200:ff:fe00:a2a2	00:00:00:00:a2:a2

TEST PROCEDURE

       NUT     TN
        |       | 
        |       | initialize NUT (as a DHCPv6 Server)
        |       | 
        | <---- | Relay-forward(Solicit)
        | ----> | Relay-reply(Advertise) (*1)
        |       | 

JUDGEMENT

(*1)PASS: The Interface-Id value of Relay-reply message is same as the
	  Relay-forward message and the Relay-reply should include the
	  Advertise message.
