=head1 NAME

	Echo_Multicast.seq - check that sending 
	and receiving Echo Request and Echo Reply (Multicast Address)

=head1 TARGET

	Host/Router

=head1 SYNOPSIS

	Echo_Multicast.seq [-tooloption ...] -p Echo_Multicast.def

=head1 INITIALIZATION

	When test starts, states of Neighbor Cache Entry for TN's 
	addresses are reachable.

=head1 TEST PROCEDURE

	This test verifies that NUT receives valid ICMPv6 Echo Request 
	and sent ICMPv6 Echo Reply. 
	

	TN			NUT

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

	1.
	 === ICMPv6 Echo Request ===>
    		src address : TN link local address
			dst address : multi cast  address        
	2.
	<< JUDGMENT >>

	 <=== ICMPv6 Echo Reply ===
    		src address : NUT global or link local address
			dst address : TN link local address        
          

=head1 JUDGMENT

	<< PASS >>
		NUT received ICMPv6 Echo Reply
		

	<< FAIL >>	
		NUT do not received ICMPv6 Echo Reply
