Implementing IPv6
IPv6 is implemented at system bootup by the script /etc/rc2.d/S69inet. This script determines whether the system is a router or a host, and starts the relevant processes. This section describes the IPv6 processes and how to configure IPv6 interfaces.
Neighbor Discovery Protocol (NDP)
The neighbor discovery protocol (NDP) is implemented in IPv6 to provide the following facilities:
Address autoconfiguration— Enables a host to automatically configure an IPv6 address for a network interface.
Address resolution— Enables a host to determine the ethernet address of a neighbor, given the neighbor's IPv6 address. (The interface identifier part of the IPv6 address is based on the ethernet address.)
Neighbor unreachability detection
