NAME

        automatic_encapsulation_host.seq - Verify that encapsulation IPv6 
        datagram in IPv4 used automatic tunnel

TARGET

        Host

INITIALIZATION

	Before this test starts, run initialize.seq.

TEST PROCEDURE

        This test verifies that NUT encapsulates an IPv6 packet in 
        automatic tunnel 

        TN                      NUT

        ---------------------------

        1.
                'ping6' command is executed by remote script 'ping6.rmt'
                        dst address : Off-link IPv4 compatible IPv6 address address

        << JUDGMENT >>

         <=== IPv4 packet encapsulating IPv6 packet ===
                Outer Header (IPv4)     
                        src address : NUT's IPv4 address        
                        dst address : Off-link IPv4 address
                Inner Header (IPv6)     
                        src address : NUT's IPv6 address        
                        dst address : Off-link IPv4 compatible IPv6 address 
 

JUDGMENT

        << PASS >>
                NUT received IPv4 packet encapsulating IPv6 packet
                

        << FAIL >>      
                NUT did not receive IPv4 packet encapsulating IPv6 packet
