The configuration below shows what I mean: ipv6 general-prefix GP 2001:DB8:2::/48 When using a general prefix in an IPv6 address assignment, you can use any hexadecimal character to represent the general prefix part, since it will be ignored. We can create general prefixes that can be referenced during address assignment and they make renumbering easier-change a general prefix and the IPv6 addresses that reference this general prefix will also change. Note: I wasn’t able to ping a link-local IPv6 address from the router in Packet Tracer even though it works on a real device – you will only need to specify a source interface.

Therefore, let’s verify connectivity between them by pinging from Host1: Since this interface and Host1 are on the same link, we should have connectivity between the two devices. With IPv6 enabled on that interface, a link-local IPv6 address will automatically be generated, as shown in the output of the show ipv6 interface brief command below: Since this task specifically states that we should not manually assign an IPv6 address, we will use the ipv6 enable command.

There are two ways to enable IPv6 on an interface: by using the ipv6 enable interface configuration command or by configuring an IPv6 address on that interface. Ensure that Host1 automatically configures an IPv6 address for itself from this prefix (2001:db8:1:aaaa::/64). Configure an IPv6 address from the 2001:db8:1:aaaa::/64 prefix on R1’s Fa0/0 interface using EUI-64 to form the interface ID.
