decapsulation_host.seq - Verify that node decapsulate IPv6
datagram in IPv4 packet
Host

Before this test starts, run initialize.seq.
This test verifies that NUT decapsulates the IPv6 packet in a IPv4
packet
TN NUT
---------------------------
1.
=== IPv4 packet encapsulating IPv6 packet ===>
Outer Header (IPv4)
src address : Off-link IPv4 address
dst address : NUT's IPv4 address
Inner Header (IPv6)
src address : Off-link IPv6 global address
dst address : NUT's IPv6 global address
2.
In NUT, received IPv4 packet is decapsulated, and NUT creates the
IPv6 Echo reply packet in response to encapsulated IPv6 Echo Request.
3.
<< JUDGMENT >>
<=== ICMPv6 Echo Reply ===
IPv6 Header
src address : NUT's IPv6 address
dst address : Offlink IPv6 global address
<< PASS >>
NUT received ICMPv6 Echo Reply
<< FAIL >>
NUT did not receive ICMPv6 Echo Reply
