    15. 15. 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
    16. 16. • Used to communicate with other devices on the link.• Are NOT routable off the link.• An IPv6 device must have at least one link-local address.• Used by:• Hosts to communicate to the IPv6 network before it has aglobal unicast address.• Used as the default gateway address by hosts.• Adjacent routers to exchange routing updatesInterface ID/641111 1110 10xx xxxxFE80::/10Remaining 54 bits10 bits 64 bitsEUI-64, Random or Manual ConfigurationLink-local unicast
