=end html Identifier The identifier from the invoking Echo Request message. Sequence The sequence number from the invoking Echo Request Number message. Data The data from the invoking Echo Request message. Description Every node MUST implement an ICMPv6 Echo responder function that receives Echo Requests and sends corresponding Echo Replies. A node SHOULD also implement an application-layer interface for sending Echo Requests and receiving Echo Replies, for diagnostic purposes. =begin html
   The source address of an Echo Reply sent in response to a unicast
   Echo Request message MUST be the same as the destination address of
   that Echo Request message.
=end html An Echo Reply SHOULD be sent in response to an Echo Request message sent to an IPv6 multicast address. The source address of the reply MUST be a unicast address belonging to the interface on which the multicast Echo Request message was received. =begin html
   The data received in the ICMPv6 Echo Request message MUST be returned
   entirely and unmodified in the ICMPv6 Echo Reply message.
