You have been asked to design and implement a network for a company with locations in four cities. Three of the locations will be connected using leased-line serial links. The fourth location, Galway, will be connected using Frame Relay because of cost considerations. The company has previously used RIP version 2 in this location and wishes to continue using it for now. However, the other three locations will use OSPF, so you must redistribute RIP routes into the OSPF routing process.
One location, Cork, has a large and complex LAN. Due to the size and complexity, the company wants you to create VLANs to control broadcasts, enhance security, and logically group users. The company also wants to use private addresses and DHCP throughout the WAN, so you must properly implement NAT for Internet connectivity. The company also wishes to limit Internet access to Web traffic while allowing multiple protocols within its own WAN.
Although private addresses (RFC 1918) will be used, the company appreciates efficiency and address conservation in design. To minimize wasted address space, they have requested VLSM to be used when appropriate.
