1. Send Packet to Link0
2. Wait Packet from Link1 or NS from Link1
3. If NS received then send NA to Link1, and wait Packet form Link1 again
4. Receive Packet from Link1
5. Send Packet to Link1

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.
