1. Check Link0 Global Address Reachability
2. Check Link1 Global Address Reachability
3. Check Global Address Reachability (from Link0 to Link1)
4. Check support of Routing Header
1. Send bad Echo Request (Link0)
2. Wait 5 sec.
3. Send Echo Request (Link0)
4. If NS received then send NA, and wait Echo Reply again (Link1)
5. Receive Echo Request (Link1)
