1. Send Echo Request to Link0 2. Wait Echo Reply from Link1 or NS from Link1 3. If NS received then send NA to Link1, and wait Echo Reply form Link1 again 4. Receive Echo Reply from Link1 5. Send Echo Request to Link1 6. Wait Echo Reply from Link0 or NS from Link0 7. If NS received then send NA to Link0, and wait Echo Reply form Link0 again 8. Receive Echo Reply from Link0
Echo Request to Link0 Data is:
IPv6 Header Version = 6 Traffic Class = 0x12 (8 bit) FlowLabel = 0 PayloadLength = 16 NextHeader = 58 (ICMP) HopLimit = 3 SourceAddress = Tester Global Address (Link0) DestinationAddress = Tester Global 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}
Neighbor Solicitation packet's IP source Address selection may be: - Link Local Address - Global Address This test IS NOT the Neighbor Discovery test, so admit both implementation.
PASS: Echo Reply Received from Link0
IPv6 Header Version = 6 Traffic Class = 0x12 (8 bit) FlowLabel = 0 PayloadLength = 16 NextHeader = 58 (ICMP) HopLimit = 2 (decremented) SourceAddress = Tester Global Address (Link1) DestinationAddress = Tester Global Address (Link0)
ICMP Echo Reply Type = 129 (Echo Reply) Code = 0 Checksum = (auto) Identifier = 0xffff (same as Echo Request) SequenceNumber = 1 (same as Echo Request) PayloadData = {1,2,3,4,5,6,7,8} (same as Echo Request)
