IPv6 ND Mechanisms
- Router discovery:Equivalent to ICMPv4 Router Discovery
- Prefix discovery:Equivalent to ICMPv4 Address Mask Request/Reply
- Parameter discovery:Discovery additional parameter (ex. link MTU, default hop limit for outgoing packet)
- Address auto-configuration: Configure IP address for interfaces
- Address resolution: Equivalent to ARP in IPv4
- Next-hop determination: Destination address, or address of an on-link default router
- Neighbor unreachable detection (NUD)
- Duplicate address detection (DAD): Determine that an address considered for use is not already in use by a neighboring node
- First-hop Redirect function Inform a host of a better first-hop IPv6 address to reach a destination, Equivalent to ICMPv4 Redirect
