1 Router (Cisco 1941 with Cisco IOS Release 15.2(4)M3 universal image or comparable)
1 Switch (Cisco 2960 with Cisco IOS Release 15.0(2) lanbasek9 image or comparable)
2 PCs (Windows 7 or 8 with terminal emulation program, such as Tera Term)
Console cable to configure the Cisco IOS devices via the console ports
Ethernet cables as shown in the topology

Part 4: Test and Verify IPv4 End-to-End Connectivity
Total points: 8
Time: 10 minutes
Step 1: Verify network connectivity.
Use the ping command to test connectivity between all network devices.
Note: If pings to host computers fail, temporarily disable the computer firewall and retest. To disable a Windows 7 firewall, select Start > Control Panel > System and Security > Windows Firewall > Turn Windows Firewall on or off, select Turn off Windows Firewall, and click OK.
Use the following table to methodically verify connectivity with each network device. Take corrective action to establish connectivity if a test fails:

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
