Objectives

  • Part 1: Configure Devices and Verify Connectivity
  • Part 2: Gather Information with Show Commands

Background

In this activity, you will configure RTA with basic settings, including IP addressing. You will also configure SW1 for remote management and configure the PCs. Once you have successfully verified connectivity, you will use show commands to gather information about the network.

Note: The user EXEC password is cisco. The privileged EXEC password is class.

Part 1: Configure Devices and Verify Connectivity

Step 1: Apply basic configurations to RTA.

a. Using the following information and the Addressing Table, configure RTA:

  • Hostname and banner
  • Line passwords set to cisco; encrypted password set to class
  • IP addressing and descriptions on LAN interfaces

b. Save the configuration.

Router>en
Router#conf ter
Router(config)#hostname RTA
RTA(config)#banner motd #This is RTA router#
RTA(config)#line con 0
RTA(config-line)#pass cisco
RTA(config-line)#login

RTA(config-line)#line vty 0 15
RTA(config-line)#pass cisco
RTA(config-line)#login

RTA(config-line)#enable secre class

RTA(config)#int g0/0
RTA(config-if)#ip add 10.10.10.1 255.255.255.0
RTA(config-if)#no sh

RTA(config-if)#int g0/1
RTA(config-if)#ip add 10.10.20.1 255.255.255.0
RTA(config-if)#no sh

RTA(config-if)#end
RTA#copy running-config startup-config
Step 2: Configure addressing on PC1 and PC2.

a. Using the Addressing Table, configure IP addressing for PC1 and  PC2.

b. Test connectivity between PC1 and PC2. Troubleshoot as necessary.

Step 3: Configure SW1 for remote management.

a. Using the Addressing Table, configure the management interface for SW1.

b. Configure the default gateway address.

c. Save the configuration.

SW1(config)#int vla 1
SW1(config-if)#ip add
SW1(config-if)#ip address 10.10.10.2 255.255.255.0
SW1(config-if)#no sh
SW1(config-if)#ip default-gateway 10.10.10.1

SW1(config-if)#end
SW1#copy running-config startup-config

Part 2: Gather Information with Show Commands

Step 1: Gather information from show interface command output.

Issue each of the following commands and then answer the related questions:

show ip interface brief
show interfaces
show ip interface

Which commands display the status of the port?

#show ip interface brief
#show interfaces
#show ip interface

Which command shows only the IP address (no subnet mask or prefix)?

#show ip interface brief

Which command displays the description configured on the interface?

#show interfaces

Which command displays the IP broadcast address?

#show interfaces

Which command displays the MAC address of the interface?

#show interfaces
Step 2: Gather information from show ip route command output.

Issue each of the following commands and then answer the related questions:

#show ip route
#show ip route connected

How many networks are known by the router based on the output of the show ip route command?
2 – 10.10.10.0/24 & 10.10.20.0/24

What does the L at the beginning of the lines within the routing table represent?
Local connection

What does the /32 prefix listed in the route table indicate?
The host address of the interface

Step 3: Gather information after an interface state is changed.

a. On RTA, shut down the Gigabit Ethernet 0/0 interface and issue the show ip route command. How many networks are displayed in the routing table now?
1 – 0.10.20.0/24

b. Attempt to ping PC1. Was the ping successful?
No

c. Issue the show ip interface brief command. What is the status of the Gigabit Ethernet 0/0 interface?
administratively down

d. Reactivate the Gigabit Ethernet 0/0 interface. Issue the show ip route command. Did the routing table repopulate?
Yes

What can be inferred about the interface status of routes that appear in the routing table?
Interfaces must be active in order to be listed in the routing table.
