Chapter8 : Lab 8.2.6 Evaluating the Prototype Test

Step 1: Identify if weaknesses are present in the design
Is the Frame Relay WAN design able to scale to meet the expected growth?
Ya, layanan Frame Relay biasanya sangat terukur. CIR tambahan dapat dibeli dan sirkuit tambahan dapat ditambahkan jika diperlukan.

Do the results of the prototype test indicate that the Frame Relay configuration will work as expected?
Karena sebuah router bertindak sebagai saklar Frame Relay simulasi, tidak ada cara untuk menguji bandwidth dan kinerja Frame Relay nyata switched jaringan. Karena tidak mungkin untuk menguji kemampuan melalui jaringan Frame Relay TSP sebenarnya ada risiko yang berkaitan dengan desain.

Chapter8 : Lab 8.2.5 Configuring and Verifying WAN Backup Links

Task 1: Build the Network. Task Complete

Step 1 Connect devices

a. Connect the routers as shown in the topology diagram. Refer to the Test Plan in Lab 8.2.2 for cabling

required.

b. For each of the routers to be configured, use the erase startup-config and the reload commands from the privileged EXEC prompt, to ensure that you are starting with a clean configuration.

Task 2: Configure Router ISPX as a Backup. Task Complete

Chapter8 : Lab 8.2.2 Creating a WAN Connectivity Test Plan

Task 1: Review the Supporting Documentation

Step 1: Refer to the WAN Design Test Plan document provided for this lab
Download the WAN Design Test Plan. What is the purpose of this WAN design test? Which elements
of the design will be tested using this plan?
The purpose of this prototype is to demonstrate the use of Frame Relay WAN links to connect a remote site router to a central site router through a router that simulates a Frame Relay switch. Backup Ethernet links from the remote site and central site to a 4th router simulate a VPN backup capability and provide an alternate path in the event that one of the Frame Relay WAN links goes down.

Chapter8 : Lab 8.1.3 Simulating WAN Connectivity

Step 1: Connect the PCs to the router console ports

a. Referring to the topology diagram, connect a console cable from PC1 to the console port on R1.

Connect a console cable from PC2 to the console port on R2.

b. Apply power to all PCs and routers.

c. Open a HyperTerminal session on each PC and establish a session to the respective router.

Chapter7 : Lab 7.3.6 Identifying Risks and Weaknesses in the Design

Task 1: Identify areas of risk and weakness in the server farm implementation
Step 1: Analyze the physical topology
Examine the server farm topology as one entity and as a part of the entire FilmCompany topology. Look for each of the risks and weaknesses listed in the chart. Describe the devices, connections, and issues that you find, or record None found if the design appears to avoid risks in that area.
Weakness Risk Description of Location and Devices
Single point of failure If a device fails, a portion of the network will be inoperable.
Large failure domain If a device or link fails, a large portion of the network will be affected
Possible bottlenecks If the traffic volume increases, there
is a potential for response time to
degrade.
Limited scalability If the network grows more rapidly than expected, a costly upgrade will be needed.
Overly-complex design If the design is too complex, the current staff will not be able to support it properly.
Other possible

Chapter7 : Lab 7.3.5 Testing a Prototype Network

Task 1: Assemble and connect component devices

Step 1: Review the Topology Diagram and the Equipment section of the test plan

a. Determine which equipment or suitable substitutes will be required to meet the objectives of the lab.

b. Modify the topology diagram as necessary to fit available equipment.

Step 2: Review the Installation Checklist provided in lab 7.3.2.

Accommodate any equipment limitations with the use of loopback addresses.

Chapter7 : Lab 7.3.3 Configuring and Testing the Rapid Spanning Tree Prototype

Task 1: Configure all devices

Step 1: Configure S1 and S2
Configure the host name, access, and command mode passwords on each switch.

Step 2: Configure interface VLAN 1
Configure the VLAN1 IP address and default gateway on each switch.
