Background / Scenario
Ping and traceroute are two tools that are indispensable when testing TCP/IP network connectivity.
Ping is a network administration utility used to test the reachability of a device on an IP network. This
utility also measures the round-trip time for messages sent from the originating host to a destination
computer. The ping utility is available on Windows, Unix-like operating systems (OS), and the Cisco
Internetwork Operating System (IOS).
The traceroute utility is a network diagnostic tool for displaying the route and measuring the transit
delays of packets travelling an IP network. The tracert utility is available on Windows, and a similar
utility, traceroute, is available on Unix-like OS and Cisco IOS.
In this lab, the ping and traceroute commands are examined and command options are explored to
modify the command behavior. Cisco devices and PCs are used in this lab for command exploration.
Cisco routers will use Enhanced Interior Gateway Routing Protocol (EIGRP) to route packets
between networks. The necessary Cisco device configurations are provided in this lab.
Note : The routers used with CCNA hands-on labs are Cisco 1941 Integrated Services Routers (ISRs)
with Cisco IOS Release 15.2(4)M3 (universalk9 image). The switches used are Cisco Catalyst 2960s
with Cisco IOS Release 15.0(2) (lanbasek9 image). Other routers, switches and Cisco IOS versions
can be used. Depending on the model and Cisco IOS version, the commands available and output
produced might vary from what is shown in the labs. Refer to the Router Interface Summary Table at
the end of this lab for the correct interface identifiers.
Note : Make sure that the routers and switches have been erased and have no startup configurations.
If you are unsure, contact your instructor.

Required Resources
 3 Routers (Cisco 1941 with Cisco IOS Release 15.2(4)M3 universal image or comparable)
 2 Switches (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 cables to configure the Cisco IOS devices via the console ports
 Ethernet and serial cables as shown in the topology

Build and Configure the Network
In Part 1, you will set up the network in the topology and configure the PCs and Cisco devices. The
initial configurations for the routers and switches are provided for your reference. In this topology,
EIGRP is used to route packets between networks.
