If the answer is no for either question, troubleshoot the router configurations to find the error.

Then issue the pings again until the answer to both questions is yes.

Step 8: Configure PPP authentication on R1 with CHAP

a. Configure the CHAP username and password on the R1 router. The username must be identical to

the hostname of the other router. Both the password and usernames are case-sensitive. Define the

username and password to expect from the remote router. On Cisco routers, the secret password

must be the same for both routers.

Router1(config)#username Router2 password cisco

Router1(config)#interface serial 0/1/0

Router1(config-if)#ppp authentication chap

Router1(config-if)#end

Router1#

Step 9: Configure PPP authentication on R2 with CHAP

a. Configure the CHAP username and password on the R2 router. The passwords must be the

same on both routers. The username must be identical to the hostname on the other router. Both

the password and user names are case-sensitive. Define the username and password to expect

from the remote router.

Router2(config)#username Router1 password cisco

Is there an EIGRP route to the Edge2 network 172.18.3.0/24? __________ Tidak

Is there a floating static route? __________ Ya

What is the AD of this route? __________ 130

What is the next hop IP address to get to the 172.18.3.0/24 network?

__________________________________________ 172.18.225.250 (ISPX Fa0/0)

Step 4: Test IP connectivity between routers Edge2 and BR3 via the backup Ethernet link

a. Ping from PC1 on Edge2 to the IP address of host PC2.

Was the ping successful? __________ Ya

If not, troubleshoot until successful.

Verify that traffic is taking the backup link by using the tracert command from PC1 to PC2. Record the results in the WAN Design Test Plan section Test 2: Results and Conclusions.

Turn off any debugging using the undebug all command.

Step 5: Clean up

Erase the configurations and reload the routers. Disconnect and store the cabling. For PC hosts that are

normally connected to other networks (such as the school LAN or to the Internet), reconnect the

appropriate cabling and restore the TCP/IP settings.

Task 8: Reflection / Challenge

When is it most important to have a backup link? How does a backup link compare to a redundant link?

Link Backup diperlukan ketika hilangnya link primer yang akan menyebabkan hilangnya akses ke sumber daya kritis. Ini adalah biaya / resiko keputusan yang dibuat oleh sebuah organisasi.

 

This lab uses the RIP dynamic routing protocol and floating static routes to demonstrate primary and backup routes. Would it be possible to use all static routes and no dynamic routing protocol?

Ya, tapi rute statis untuk semua lokasi jaringan harus ditetapkan untuk komunikasi end-to-end
antara jaringan. Harus ada rute untuk mencapai tujuan jaringan dan rute di tempat tujuan untuk kembali, agar
komunikasi dua arah terjadi.

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.

 

Are there any weaknesses associated with using the VPN connections as backup to the Frame Relay WAN?

Walaupun pengujian memverifikasi bahwa fungsi Ethernet berbasis simulasi backup, ini tidak cukup mensimulasikan penggunaan link VPN sebagai link Fast Ethernet jauh lebih cepat daripada VPN khas. Daerah yang paling kritis risiko adalah kinerja dari link VPN sebagai backup dalam jaringan nyata. Apabila komponen suara dan video dari jaringan ditambahkan ke WAN lalu lintas yang ada, mungkin ada masalah kualitas layanan jika koneksi VPN harus digunakan. VPN arus melalui ISP tidak memiliki tingkat jaminan pelayanan. Selain itu, tidak memiliki mekanisme untuk menyediakan QoS. Akibatnya, link cadangan hanya bisa menyediakan konektivitas terbatas dalam hal kegagalan.

 

Will a failure of the primary link cause the FilmCompany to lose connectivity to the Stadium LAN?

Tidak, link backup dengan rute statis mengambang akan diaktifkan untuk menyediakan konektivitas ketika F primer / link R gagal.

 

Does the EIGRP authentication provide for a secure transmission of the routing updates?

Ya, meskipun penggunaan Pesan Digest 5 (MD5). Kombinasi kunci pengenal dan antarmuka yang terkait dengan pesan unik mengidentifikasi algoritma otentikasi dan kunci MD5 otentikasi digunakan.

Step 2: Determine what the risks are of not correcting the weaknesses

If, in Step 1, you identify weaknesses in the proposed design, what risks do these weaknesses present to

FilmCompany?

Risikonya adalah bahwa jaringan Frame Relay bawah beban aktual pengguna yang sebenarnya tidak akan melakukan serta link disimulasikan dalam prototipe. Juga, link VPN cadangan disimulasikan mungkin tidak bekerja seperti yang diharapkan dalam hal pemulihan menggunakan link VPN nyata bukan link FastEthernet simulasi. Penerimaan akhir dari desain mungkin harus menunggu sampai hasil instalasi pilot diketahui.

Step 3: Suggest ways that the design can be improved to reduce the risk

In what ways could the proposed design be improved to reduce the areas of risk?

Jika waktu dan uang mengizinkan, uji coba dapat dijalankan di mana sirkuit F/R sementara dengan CIR tertentu bisa dipasang dengan kerjasama layanan yang disediakan dan beban uji simulasi dapat dihasilkan pada berbagai waktu untuk memastikan kinerja di bawah tinggi -volume kondisi. Tingkat perjanjian layanan (SLA) juga bisa dinegosiasikan untuk menyediakan asuransi yang rangkaian akan bekerja seperti yang diharapkan selama periode beban puncak. Sehubungan dengan link backup VPN, pilot dapat termasuk penggunaan koneksi VPN aktual melalui link DSL ke lebih akurat menunjukkan kemampuan pemulihan dari desain yang diusulkan.

Step 4: Document the weaknesses and risks on the test plan

In the Results and Conclusions section of the test plan, record any weaknesses, risks, and suggested improvements.

Step 4: Reflection

Why do you think it is important to identify weaknesses and risks in the proposed design before presenting it to the customer? What are some reasons that weaknesses cannot be corrected?

Adalah penting untuk mengidentifikasi kelemahan dan risiko dalam desain yang diusulkan sebelum menyajikannya kepada pelanggan untuk memastikan bahwa pelanggan memahami keterbatasan prototipe dan tidak mengarah pada memiliki harapan yang tidak realistis berdasarkan prototipe. Mungkin tidak mungkin untuk mengimbangi semua kelemahan yang dapat diidentifikasi karena waktu, uang atau kendala personil. Risiko harus dianalisa dan seimbang terhadap variabel-variabel lainnya.

Tinggalkan komentar

Step 1: Collate and organize the information

a. Gather and read through all the project documents that you created in previous labs.

b. Ensure that multipage documents are together and that the pages are in the correct sequence.

Step 2: Review the existing information

Ensure that the documents are complete and contain the information specified. Any incomplete documents, or missing information that was not recorded at the time of that lab, now need to be checked and included at this stage.

Step 3: Organize the information

A project proposal typically contains the following sections:

Section Description
Executive Summary Discusses the project goals and project scope at a high level. This section demonstrates that the network vendor understands the extent of the project and the role of the network in meeting the business goals. The goal of the summary is to convince the decision-makers of the business benefits of the design. This section is typically one to two pages long.
Network Requirements Reviews the business goals and network requirements, including users and applications that need to be supported. This section often lists the business goals, in order of priority, with critical goals marked. This section includes the topologies; protocols, hardware, software, and training that are required to meet the business goals.
Current Network Environment Documents the state of the existing network. This section includes physical and logical diagrams and the IP addressing scheme. The section summarizes the results of the network characterization, including strengths and weaknesses of the existing network. It also documents the user community and applications currently in use, based on the network characterization.
Proposed Physical Design Describes the physical layout of the proposed design. This sectiondocuments trade-offs made to accommodate business goals and technical requirements. The section describes the features and recommended uses for the technologies and devices proposed for the new network design. This section documents the new WAN service and new network equipment. The section also includes proposed network diagrams.
Proposed Logical Design Describes the logical topology of the proposed network. This sectiondocuments any proposed addressing and naming conventions. It describes the routing and switching protocols recommended for the planned network. This section includes recommended security mechanisms and products that support the security policy of the business. The section may include information on recommended network management procedures and applications.
Implementation Plan Provides a detailed list of the tasks that must be performed to install and implement the new network. This section includes tasks, steps, time required, and proposed schedules.
Cost Proposal Provides cost proposal for equipment, software, installation, and ongoing

Step 4: Edit and finalize the information

a. Review all the materials to ensure that they are complete. It is important that the FilmCompany   management and technical staff are able to easily find and understand the material contained in the proposal. A disorganized or incomplete proposal can cause the customer to choose another contractor to complete the project.

b. Ensure that all the information has a consistent format and style. If necessary, edit or rewrite sections

so that the proposal has the appearance of a single document and not a set of separate documents.

c. Complete diagrams and other graphics and finalize what is to be included in the proposal.

d. Clearly note those sections of the proposal that have to be completed; these sections will be compiled

in the following labs.

e. Save the word processing documents and file the hardcopy information in your portfolio.

Step 1: Determine the tasks to implement the network design

Implementing a network design requires the completion of a set of tasks, such as installing hardware,

configuring systems, testing the network, and launching the network into production. Each task consists of several steps.

Each task requires the following documentation:

  • • A description of the task
  • • References to design documents
  • • Detailed implementation guidelines
  • • Detailed rollback guidelines in case of failure
  • • The estimated time required for implementation
  • • Completion sign-off

Analyze the FilmCompany network design documentation that you have compiled in previous labs. Determine and list the three main sets of tasks required to be performed to implement the network upgrade. These sets of tasks will be referred to as phases.

Phase 1

____________________________________________ Install Distribution and Core Layer equipment

____________________________________________ Configure new IP addressing & VLAN scheme

____________________________________________ Configure routing

Phase 2

____________________________________________ Upgrade the WAN connectivity

____________________________________________ Extend the network to the remote site

____________________________________________ Configure ACLs & security

Phase 3

____________________________________________ Install wireless/mobility network

____________________________________________

Step 2: Note identified success and failure criteria

When implementing a design, the possibility of a failure must be considered – even after a successful pilot or prototype network test. Each step of the implementation may require additional testing to ensure that the network operates as designed.

In the Reflection section in Chapter 2, Lab 2.3.3, you considered success criteria when determining the

objectives of the FilmCompany network upgrade. List two or three success or failure criteria for each phase of the project.

Phase 1

____________________________________________

____________________________________________

____________________________________________

Phase 2

____________________________________________

____________________________________________

____________________________________________

Phase 3

____________________________________________

____________________________________________

____________________________________________

Step 3: Include provision for customer approval

The Implementation Plan details the work required to accomplish the project goals. The plan includes the

customer expectations and the success criteria for customer approval and project sign-off. As soon as customer approval of the implementation plan is obtained, the installation can begin. The customer is given a detailed list of all devices required and the work to be completed. This list forms part of the Implementation Plan. A signed copy of this list is kept by the network designer and account manager.

Upon completion of each task, the customer is required to sign off that the work was completed and that the results are as expected.

a. Include in the documentation a signature page for an authorized FilmCompany representative to sign

and approve the Implementation Plan.

b. Include in the documentation a signature page at the end of each task for an authorized

FilmCompany representative to sign and accept the completion of each task.

Step 4: Document Phase 1

Step 5: Document Phase 2

Step 5: Document Phase 3

Step 1: Compare the installation methods

There are three possible installation methods:

  • New installation, commonly referred to as a green field installation
  • Phased installation into an existing, functioning network
  • Complete replacement, commonly referred to as a fork-lift upgrade

Consider and list the advantages and disadvantages of the three installation methods.

New Installation

Advantages:

Semua peralatan dan layanan dapat diinstal dan diuji pada saat yang sama.

Rencana implementasi untuk jaringan baru kurang kompleks dibandingkan dengan dua jenis instalasi.
Jadwal lebih fleksibel daripada ketika jaringan yang ada di tempat.
Ada gangguan minimal terhadap perusahaan.

Disadvantages:

Modal besar karena semua peralatan dan layanan yang diinstal pada waktu yang sama.

Phased Installation into Existing Network

Advantages:

Bagian-bagian dari upgrade jaringan diimplementasikan dalam isolasi dari bagian yang sedang berjalan.
Upgrade jaringan dibagi menjadi potongan-potongan kecil yang dapat diinstal dan diuji dengan cepat.
Instalasi upgrade secara bertahap yang lebih kecil menyebabkan sedikitnya jumlah downtime.

Disadvantages:

Sebuah penerapan secara bertahap membutuhkan perencanaan yang lebih rinci dengan pelanggan.

Complete Network Replacement

Advantages:

Jaringan yang ada bisa tetap beroperasi sepenuhnya sampai jaringan pengganti dibawa ke dalam produksi.

Disadvantages:

Kedua jaringan mungkin beroperasi secara paralel untuk beberapa waktu, yang meningkatkan biaya operasi dan dapat menyebabkan kebingungan dan dukungan bagi pemakai

Step 2: Select the installation method

Two of the FilmCompany requirements are:

  • • The company network services must be available during the upgrade.
  • • Existing equipment must be used in the new network design.

Select the appropriate installation approach for the FilmCompany network upgrade.
