E-Switching Case Study, v5.3.1a

VLANs, Wireless, Router & Switch Configuration PHASE I – IP Addressing and VLANS The Carl I. Samson Company (C.I.S. Co) of Bangor, Maine has recently been acquired by CorpHQ in

Detroit Michigan. Prior to the merger C.I.S. Co had been running a RIP based network with an IP

address of 169.254.40.0/21 equally sub-netted to support their users in Phoenix, Chicago and Bangor.

CorpHQ requires that all subsidiaries use the company standard EIGRP as a routing protocol.

Additionally CorpHQ has allocated the network address of 172.25.64.0./20 for the internal networks

in the C.I.S. Co division. Internet access for the C.I.S. Co LAN is through the Border Router that is

part of the Bangor LAN.

The C.I.S. Co. IT Director wants to more efficiently allocate IP addresses and consequently has

implemented Variable Length Subnet Masking. They have implemented trunked Virtual Local Area

Networks (VLANs) to streamline cabling and switch-port allocation, which allows easier moves,

adds and changes in the network while increasing security. Your job is to configure all of the routers,

switches, Access points, and PCs to support the new design.

Refer to Table 1 for a breakdown of the assigned networks and VLANS, and the network diagram for

the new network topology.

PHASE II - Router Configuration

The following table outlines the configuration tasks you need to perform on the routers in the

topology. Where specific configurations are required they are noted below; otherwise it is to

your discretion which names and/or addresses you will use.

The Bangor wireless access point has an SSID of Bangor and no encryption. The Bangor

wireless laptop has already been configured with an IP address but needs an SSID.



PHASE III - Switch & Access Point Configuration

topology. Where specific configurations are required they are noted below; otherwise it is to

your discretion which names and/or addresses you will use.

PHASE IV – Host Configuration Configure all workstations and servers with appropriate IP addresses, subnet masks, default

gateways, and DNS servers. Where appropriate also set the SSID.

Note: The Phoenix wireless clients will use DHCP from the Phoenix wireless router.

PHASE V - Test Confirm that all workstations, routers, and switches can ping each other, their local default

gateways and the Internet addresses of www.cisco.com and www.msn.com. Confirm that

workstations can SSH to the routers and telnet to the switches.
