1. TN1 transmits an Echo Request to TN2's Global unicast Address with a first hop through the RUT.
The source address is TN1's Global address.
2. Observe the packets transmitted by the RUT on Link1.
Echo Request Data is:
IPv6 Header
Version = 6
Traffic Class = 0
FlowLabel = 0
PayloadLength = 16
NextHeader = 58 (ICMPv6)
SourceAddress = TN1 Global Address (Link0)
DestinationAddress = TN2 Global unicast Address (Link1)
ICMP Echo Request
Type = 128 (Echo Request)
Code = 0
Checksum = (auto)
Identifier = 0xffff
SequenceNumber = 1
PayloadData = {1, 2, 3, 4, 5, 6, 7, 8}
PASS: The RUT must forward the Echo Request from TN1 to TN2 with a first hop through the RUT.
