A Unified Stateful/Stateless Configuration Service for IPv6
draft-templin-6man-dhcpv6-ndopt-11
Abstract
IPv6 Neighbor Discovery (IPv6ND) specifies a control message set for
nodes to discover neighbors, routers, prefixes and other services on
the link. It also supports a manner of StateLess Address
AutoConfiguration (SLAAC), while the Dynamic Host Configuration
Protocol for IPv6 (DHCPv6) specifies a separate stateful service.
This document presents IPv6ND extensions for providing a unified
stateful/stateless configuration service.
