Err_Msg_Size_Dst_Unreach_4.seq - check Message Processing Rules (ICMPv6
Destination Unreachable , link local address)
Host/Router
Err_Msg_Size_Dst_Unreach_4.seq [-tooloption ...] -p Err_Msg_Size_Dst_Unreach_4.def
When test starts, states of Neighbor Cache Entry for TN's
addresses are reachable.
This test verifies that the message processing rule ,
Every ICMPv6 error message (type < 128) includes as much of the
IPv6 offending (invoking) packet (the packet that caused the
error) as will fit without making the error message packet
exceed the minimum IPv6 MTU [IPv6].
