Alternative Media for Cisco & Juniper Certifications

The Journal of Networking is created as an alternative media for understanding and learning the computer network knowledges. Most of the articles are base on Cisco & Juniper material/student guide. This journal also want to encourage people become certified in their IT industry field.
For now on, we are try to discussing ICND1v1.0, ICND2v1.0, CSEv4.0, BSCIv3.0, BCMSNv3.0, ISCWv1.0, ONTv1.0, QoS, BGP, MPLSv2.2 and CJFV material.
Have a nice collaborating!

[Exercise] IP Management Part 3

Dibawah ini adalah contoh kasus penerapan pengelolaan Internet Protocol (IP) menggunakan tehnik Variable Lenght Subnet Mask (VLSM).

PROJECT 1: Sebagai network engineer Anda diminta untuk membuat disain jaringan dengan kebutuhan jaringan sebagai berikut: 8 departemen yang terdiri dari 2 departemen masing-masing sebanyak 120 komputer, 2 departemen masing-masing sebanyak 28 komputer, 4 departemen masing-masing sebanyak 6 komputer. Anda juga diingatkan untuk membuat jaringan point-to-point antar router yang telah dibeli oleh client Anda.

PROJECT 2: Sebagai network engineer Anda diminta untuk membuat disain jaringan dengan kebutuhan jaringan sebagai berikut: 8 departemen yang terdiri dari 2 departemen masing-masing sebanyak 502 komputer, 2 departemen masing-masing sebanyak 120 komputer, 4 departemen masing-masing sebanyak 18 komputer. Anda juga diingatkan untuk membuat jaringan point-to-point antar router yang telah dibeli client Anda.

PROJECT 3: Sebagai network engineer Anda diminta untuk membuat disain jaringan dengan kebutuhan jaringan sebagai berikut: 8 departemen yang terdiri dari 1 departemen masing-masing sebanyak 200 komputer, 4 departemen masing-masing sebanyak 40 komputer, 3 departemen masing-masing sebanyak 15 komputer. Anda juga diingatkan untuk membuat jaringan point-to-point antar router yang telah dibeli client Anda.

[Exercise] IP Management Part 2

A basic question ( using subnet zero's + subnet one's! )

  1. What is the class IP of the numbers ?
  2. How many network bits are there ?
  3. How many host bits are there ?
  4. How many host bits borrowed?
  5. How many available subnet ?
  6. How many available host ?
  7. What is the subnet mask for the numbers ?
  8. How many interval for each subnet ?
  9. What is the subnet id for the numbers ?
  10. What is the broadcast id for the numbers ?
  11. What are the available hosts ?
  12. What are the available hosts for the second subnet ?
  13. Is it public IP Addresses -or- private IP Addresses ?
  14. Define the number! (Is it IP Address? Network Address? -or- Broadcast Address?)

Exercises:

Define Internet Protocol below, using 14 question above!

a. 10.1.1.52/28

b. 172.16.125.8/19

[CCNA] Network Address Translation

Lab: Network Address Translation (NAT)
 
Scenario: Hub and Spokes, NAT using PAT
Connections: Internal Networks to External Network
Minimum requirements: 2 router and 1 switch
NOS: IOS version 12.x
Objective: Showing NAT table
Amount of Task: 2
 
Task 1: Configurations
 
router(config)#int s0/0/0
router(config-if)#ip nat outside  --> interface s0/0/0 as an outside interface
router(config-if)#no shutdown
 
router(config)#int fa0/0
router(config-if)#ip nat inside  --> interface fa0 as an inside interface
router(config-if)#no shutdown
 
router(config)#access-list 10 permit 10.y.y.0 0.0.0.255  --> allowing hosts cross over the boundary router
router(config)#ip nat inside source list 10 interface s0 overload  --> using PAT configuration
 
switch#ping 10.1.1.3 --> from your switch or host, make traffic out of your router
switch#ping 10.1.1.1 --> make traffic out of your router
 

Task 2: verifications
 
router#show ip nat translations  --> membaca table NAT
router#show ip nat statistics
 
switch#ping 10.140.z.2 --> success?
switch#ping 10.z1.z1.3  --> success?
switch#ping 10.z1.z1.11 --> success? why?
 

legend:
x = your group pod
y = your group pod + 1 = internal networks
z = your partner's group pod
z1 = your partner's group pod + 1
