Checking Lab Challenge 4 (VTP, STP, EtherChannel, NAT, OSPF, HSRP)

April 23rd, 2016

Introduction

You are tasked to check the network configuration of a new company and answer some related questions. This company has four switches and four routers connected as shown in the topology. Because of security reasons, the traceroute commands are disabled on all devices.

Note: You are not allowed to configure anything by company policy. The network is operating correctly so just use various “show” commands to learn how this network works.

This lab is good to help you understand how a simple network with routers and switches work together. But it includes many CCNA topics so you should grasp the concept well before taking this lab challenge.

The topology of this lab is shown below.

Refer to the exhibit. You are tasked to configure Internet access for the users in your company. Your ISP has given you six public IP addresses in the range of 45.9.1.65 45.9.1.70/29 .
Your company has 62 hosts that need to access internet at the same time. They are using private IP addresses in the 172.16.4.65 – 172.16.4.126/26 range.

Basic router configuration has been configured. Your tasks are:
