CCNA-1.12: Identify the appropriate IPv6 addressing scheme to satisfy addressing requirements in a LAN/WAN environment (LAB)

IPv6 addressing is designed differently than IPv4.  Subnetting is used in IPv4 to more efficiently use the small number of available addresses. IPv6 has a large enough address space without subnetting to accommodate devices for the foreseeable future.  The local area subnet always uses 64 bits for the routing prefix and 64 bits for the host, which is known as the interface identifier. 2000::/3 is the IPv6 Global Unicast range based on RFC4291

  • Configuring Manual IPv6 on our Internetwork
    • On Router1
        • Enable IPv6

      config t
      ipv6 unicast-routing

        • On loopback0, configure IPv6 address 2000:3d81:90bc:1:42:a9FF:FE92:1977/64

      interface lo0
      ipv6 address 2000:3d81:90bc:1:42:a9FF:FE92:1977/64

        • On loopback1, configure an IPv6 address by using the extended unique identifier (EUI-64), which allows the interface to use its MAC address and pad it to make the interface ID

      interface lo1
      ipv6 address 2000:3d81:90bc:2::/64 eui-64

        • On loopback2, configure an automatic IPv6 link-local address

      interface lo2
      ipv6 enable

        • Verify the ipv6 addresses
