ICMPv6 Type 129 corresponds to which message?

Explanation:
ICMPv6 assigns specific numeric types to each message. The Echo Request used by ping has type 128, and its reply has type 129. The other two values shown are for Neighbor Discovery messages: Router Solicitation is type 133 and Router Advertisement is type 134. Therefore, a message with type 129 is the Echo Reply, the response you get to an Echo Request.
