Stateless Autoconfiguration (EUI-64)

[Reference: R&S Study Guide, 2nd Edition Ch. 14 Pg. 556]

SLAAC (State Less Automatic Address Configuration):

Stateless Autoconfiguration is a useful solution because it allows devices on a network to address themselves with a link-local unicast address as well as with a global unicast address. This process happens through first learning the prefix information from the router and then appending the device’s own interface address as the interface ID.

To perform auto-configuration, a host goes through a basic two-step process:

  1. First, the host needs the prefix information, similar to the network portion of an IPv4 address, to configure its interface, so it sends a router solicitation (RS)request for it. This RS is then sent out as a multicast to all routers (FF02::2). The RS message is ICMP type 133.
  2. The router answers back with the required prefix information via a router advertisement (RA). An RA message also happens to be a multicast packet that’s sent to the all-nodes multicast address (FF02::1) and is ICMP type 134. RA messages are sent on a periodic basis, but the host sends the RS for an immediate response so it doesn’t have to wait until the next scheduled RA to get what it needs.

What is the problem with StateLess Automatic Address Configuration (SLAAC)?

  • With SLAAC, by default, no DNS configuration is returned to the host.

DHCPv6 (Stateful) (IP and Options)

[Reference: R&S Study Guide, 2nd Edition Ch. 14 Pg. 559]

– Static
– Stateful DHCP (IP and Options)
– Stateless DHCP (no IP, just Options) [DNS, Domain you belong to.] (Used with SLAAC)

  • If you are using the hardcopy, instead of the the Template, enter your answers in pencil, in case you have to make changes.
    • Make sure to write as neat as possible so that I can read your answers.
    • Use a pencil!
    • If you insist on using a pen, and you have to make changes, use whiteout instead of crossing out and making a mess.

Hands-on Lab-11 (Chapter 15) @

This lab will assume that you have added VLANs 2 and 3 to each of your switches and all of your links are trunked.

Configure the 2960 switch connections as listed below

  • S1 Fa0/1  => S2 Fa0/1
  • S1 Fa0/2  => S3 Fa0/1
  • S2 Gi0/1  => S3 Gi0/1
  • S2 Gi0/2  => S3 Gi0/2
  • S2 & S3 use Fa0/2 for PCs

Lab Notes

  • Do 15.1, 15.2, 15.3, and 15.4
  • Using Cisco Packet Tracer v7.2 or newer.
  • Use three 2960 switches.
  • You must be in class to get credit for completing this lab.
  • You will need your text book for the Hands-on lab instructions.
