Understanding IPv6 Neighbor Discovery

This section describes the IPv6 ND and SEND mechanisms.

IPv6 ND: IPv6 neighbor discovery (ND) uses ICMPv6 messages to implement address resolution, verify neighbor reachability, detect duplicate addresses, discover routers and prefixes, automatically assign addresses, and perform the redirection function.

IPv6 SEND: This section describes the IPv6 Secure Neighbor Discovery (SEND) protocol.
