Dst_Unreach_0_Global.seq - check ICMPv6 Destination Unreachable code 0
Router
Dst_Unreach_0_Global.seq [-tooloption ...] -p Dst_Unreach_0_Global.def
When test starts, states of Neighbor Cache Entry for TN's addresses are reachable.
This test verifies that NUT sends valid ICMPv6 Destination Unreachable (code 0) in response to a packet which can not be delivered to destination address because NUT have no route. And this test verifies that the message processing rule ,
If the message is a response to a message sent to one of the node's unicast addresses, the Source Address of the reply must be that same address.
