Scenario

Castle Entertainment sells tv/movie memorabilia. The owner (who still wishes to remain anonymous but goes by the name of Richard) has decided that now is right time to once again update his networking infrastructure.

Richard now believes in an open plan where every department to be located on the same floor. Richard also wants to adopt the IPv6 protocol.

Richard's Requirements

Sales department (7 employees in total), Administration and Billing (4 employees in total) and Richard's three receptionists should all be on separate networks. Richard will also need his own private network which he wants to be wireless. All other networks will be wired only.

Standard PCs will be used by all department except for Richard himself who will continue using a laptop

Castle Entertainment has been allocated the IPv6 address: 2001: ABCD: DCBA:6660::/60 by their ISP.

Richard knows how expensive networking equipment can be, so he only wants one router for the entire company. Richard can live with a few switches but recently has heard of this VLAN thingy.

Castle Entertainment is about to be audited and Richard wants the auditor to have a wireless connection from their laptop to the network. Please add the auditor to Richards's private network.

Richard wants to be able to ping any sales person's computer from his laptop at any time.
