ICMPv6 stands for Internet Control Message Protocol version 6. It’s the IPv6 implementation of the Internet Control Message Protocol (ICMP). The ICMPv6 protocol defines various message types and formats which implement different IPv6 protocols such as Neighbor Discovery Protocol (NDP).

FreeRTOS+TCP uses ICMPv6 messages as a framework to implement RA, Neighbor Discovery Protocol (NDP) and ICMPv6 echo ping request/reply.
