1. IPV6 ADDRESS TYPES

   • UNICAST
     • LINK LOCAL (LLA)
       • IPV6 ADDRESS FE80::1:1 LINK LOCAL
       • DYNAMIC ADDRESSING
         • ID INTERFACE
         • CISCO ROUTERS AUTOMATICALLY CREATES LLA WHEN
           • GUA IS ASSIGNED TO THE INTERFACE
           • BY DEFAULT USES EUI-64 TO GENARATE THE INTERFACE ID
             • EXCEPTION : SERIAL INTERFACE WILL USE MAC ADDRESS OF AN ETERNET INTERFACE
         • ID DE REDE ( LLA )
       • FE80::10
       • NOT INCLUDED IN THE ROUTING TABLE
       • SAME METHODS AS THE GUA
     • GLOBAL UNICAST (GUA)
       • R1(CONFIG-IF)#IPV6 ADDRESS 2001:db8:acad:1::1/64
       • DYNAMIC ADDRESSING
         • HOW DO THEY GET IT?
           • HOW DO THEY GET IT ? THROUGH ICMPV6 (INTERNET CONTROL VERSION 6)
             • MESSAGE ROUTE ADVERTISEMENT ( RA )
               • 1) SENT TO ALL IPV6 ROUTERS BY
                 • HOSTS REQUESTING ADDRESS (RS)
               • 2 ) SENT TO ALL IPV6 NODES
               • 3 - MÉTODOS
                 • SLAAC - STATELESS
                   • MESSAGE RA INCLUDES
                     • NETWORK PREFIX ; PREFIX LENGHT
                     • GATEWAY
                       • IPV6 LLA

                       • GENERATING A RANDOM 64BIT NUMBER
                       • PC USES SLAAC TO OBTAIN PREFIX AND CREATES ITS OWN INTERFACE ID
                   • CREATES ITS OWN GUA WITHOUT SERVICES DHCPv6
                 • DHCPV6 STATELESS

                     • NETWORK PREFIX ; PREFIX LENGHT
                     • GATEWAY
                       • IPV6 LLA
                   • SERVER
                     • DNS & DOMINIO
                     • SERVER IT DOES NOT ALLOCATE GUAs
                   • HOW THE ADDRESS IS CREATED ?
                     • INTERFACE ID
                       • PC USES SLAAC TO OBTAIN PREFIX AND CREATES ITS OWN INTERFACE ID
                       • EUI-64 PROCESS

                   • ALLOCATES AND MANTAINS A LIST OF WHICH DEVICE RECEIVES IPV6
                   • CLIENT DOES NOT NEED TO GENERATE ITS INTERFACE ID
               • 1 ) ROUTERS PERIODICALLY SEND
                 • MESSAGE EVERY 200 SECONDS
               • THESE MESSAGES ARE IN THE ROUTER INTERFACES
                 • SO WE MUST FIRST ENABLE THE INTERFACE
