R1DHCPv6 Server• Neighbor Discovery Protocol• The router’s Router Advertisement (RAs)determines how thehost gets its dynamic address configuration.• ipv6 unicast-routing command enables router to send RAs.• Default = Stateless Address Auto Configuration (SLAAC)• Router uses ICMPv6 to deliver IP address & D.G. via RA.• Other Options:• Stateless DHCPv6 – delivers only additional info (e.g. DNS)• Stateful DHCPv6 – delivers all IP infoRA  RS DNS info
