Tasks:

Configure the network in the diagram above following the specifications outlined below.

Basic IP configuration:

You have been allocated the class C network 192.168.1.0/24 for use in this network. This

network must be divided to support the following requirements:

R1- R3 LAN connection: support a maximum of 60 hosts

R2 LAN connection: support a maximum of 30 hosts

WAN connections between R1/R2, R2/ R3: Minimize the number of IP addresses used (2

hosts)

R1 loopback interface:1.1.1.1/32

R2 loopback interface:2.2.2.2/32

R3 loopback interface:3.3.3.3/32

Router Configurations:

1. Assign IP addresses to each interface as determined in the IP addressing section.Use the first available address in the interface subnet space when possible. Clearly

document these addresses on your lab diagram.

2. Configure OSPF between R1, R2 and R3. All interfaces should be advertised to therest of the network.

3. Configure OSPF authentication between WAN links using encryption. Use cisco

as the authentication password.

4. Modify the cost of the link between R2 and R3 to be 100.5. Secure the routers using cisco as the enable, telnet, and console password.

6. Verify all routes.

Part 1 AssessmentThe individual will be graded on the following performance items. These items may

be performed on any of the workstations or routers. This part is pass/fail.

Performance Item R1 R2 R3

Design IP addressing Scheme. IP addressing scheme meets

requirements outlined in Part 1.

OSPF configuration. OSPF is configured and advertising all

interfaces/networks.

Ping router interface from router. Ping an interface IP address

on any router from any other routerOSPF authentication. OSPF routers successfully authenticateeach other.

Link Cost. OSPF cost has successfully been changed to 100 on

the link between R2 and R3.

Telnet to all routers by router host name. Telnet from one

router to each of the other routers using their host name and be

able to show all telnet sessions to other routers simultaneously.

Part 2: LAN Switching

LAN Switch Configuration:

1. Configure VLAN 10 as the management VLAN on SW1 and place the interface

using the IP address shown in the diagram.

2. Configure VLAN 20 as the management VLAN on SW2 and place the interfaceusing the IP address shown in the diagram.

3. Configure the link between SW1 and SW2 to use VLAN 20.

4. Configure a trunk link between R2 and SW1 in order to facilitate inter-VLANrouting between VLAN 10 and 20. Use the first available IP address in each subnet

on the router interfaces.

5. Secure the switch using cisco as the enable, telnet, and console password.

6. All devices in the network should be able to telnet and log-in to this switch.

Performance Item R2 SW1 SW2

VLAN configuration. Management VLAN is created and ports

assigned to appropriate VLAN.

Trunk configuration. Trunk is configured between router and

switch.

Ping/Telnet to all devices. Ping and telnet from one router to
