TEST PROCEDURE

Verify that a node properly forwards the ICMPv6 Echo Requests.

             (Link1)         (Link0)
       TN2             RUT             TR1             TN1
        |               |               |               |
        |---------------+---------------+-------------->| Echo Request
        |               |               |               |
        v               v               v               v

  1. TN2 transmits an ICMPv6 Echo Request to TN1's Site-local address with a first hop through the RUT.
     The source address is TN2's Global address.
  2. Observe the packets transmitted by the RUT.

  Echo Request Data is:

        IPv6 Header
            Version            = 6
            Traffic Class      = 0
            FlowLabel          = 0
            PayloadLength      = 16
            NextHeader         = 58 (ICMPv6)
            SourceAddress      = TN2 Global Address (Link1)
            DestinationAddress = TN1 Site-local Address

        ICMP Echo Request
            Type           = 128 (Echo Request)
            Code           = 0
            Checksum       = (auto)
            Identifier     = 0
            SequenceNumber = 0
            PayloadData    = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08 }

JUDGEMENT

  PASS: The RUT must forward the Echo Request to TR1.
