FOR IMMEDIATE RELEASE

BOSON RELEASES NETSIM FOR CCNP VERSION 6.1 Nashville, Tennessee, May 1, 2007 - Boson Software, LLC, a provider of premier learning solutions for IT professionals seeking certification, announced today the release of Boson NetSim for CCNP 6.1. Boson NetSim is a software-based network simulator that allows the user to design and accurately test a Cisco network. Boson NetSims Virtual Packet Technology makes this software superior to others because it actually simulates the functions of the Cisco Internetworking Operating System (IOS). This technology creates individual packets that are routed and switched through the simulated network, allowing the Boson NetSim to build an appropriate virtual routing table, and simulate true networking. Boson NetSim for CCNP 6.1 includes 10 new Advanced Labs that focus on a variety of skills and technologies essential for our customers to achieve their CCNP certifications, said Chad Altman, Senior Software Engineer. I am very proud to say these labs are the best and most advanced labs we have ever released. The Boson NetSim also includes a comprehensive lab menu that contains lessons and labs covering Routing Protocols, Cisco Devices, Switching, Topological Design, and much more. The Boson NetSim for CCNP 6.1 is available online at www.boson.com or you can call 877-333-EXAM (3926) for more information. Boson Software, LLC is a privately-held company with offices in Tampa, Florida, and Nashville, Tennessee. Boson specializes in providing robust learning solutions, including the NetSim Cisco network simulator and the ExSim examination preparation materials used by individuals, businesses, academic institutions, and government entities around the world. Boson offers instructor-led training through its affiliate Boson Training, LLC for Cisco technologies, as well as for security technologies including EC Council's Certified Ethical Hacker program. ###

BOSON NETSIM FOR CCNP ROUTING
LAB 2 OPTIMIZE ADDRESSING LAB (VLSM)

Boson CCNP Routing

Objectives
Use VLSM to subdivide a Class C address and to maximize addressing efficiency
NOTE: Upon completion of this lab. We will return the routers back to the initial configuration. Make sure that you have a copy of each routers config in a text file

Command Summary
Command configure terminal show ip route ip address ip_address no ip address ip_address enable disable exit show ip interface brief erase startup-config show running-config
Description enter global configuration mode displays the IP routing table set the IP address to the value ip_address removes an IP address from an interface enter Privileged mode return to User mode back up one level in the menu structure displays a brief summary of interface status and configuration deletes the startup-config file in NVRAM view the active configuration file

Task 1 Network Analysis
1. Log on to each of the routers in your pod, issue the command show ip route. Note the size of the subnets in the route table. Using /24 subnetting, how many hosts are allowed per network ? ______________________________________________________________ 2. Which networks are wasting address space? Hint, these networks only have 2 hosts. ______________________________________________________________
Task 2 Planning New Address Space
1. What type of routing protocol is required to implement a VLSM design? ______________________________________________________________ 2. What routing protocol is in use? ______________________________________________________________ 3. For grading purposes please refer to the solution on page 7.
SCENARIO: The customer has been forced into using valid IP addressing on the public Internet by special application requirements. The Internet Service Provider has allocated a single class C address to each customer. The class C address to be used is: 195.10.1.0

Task 3 Readdressing the Network
1. Remove the current private address space. 2. Re-configure the network using the new VLSM address plan 3. Configure Rip to route for the new network 4. R1 FastEthernet 0/0 should remain 10.100.100.1

Task 4 Verification

1. Log on to each of the routers in your pod, issue the command show ip route. Note the size of the subnets in the route table. Note the new IP addresses and subnet masks in use. 2. Use the command show ip interface brief to verify the interface IP addresses are correct 3. Ensure that you have full IP connectivity within your pod. 4. If you followed the IP Address solution on page 7 you can verify your solution using the Grade Me feature in the Lab Navigator.

Task 5 Return Routers to Initial configuration
1. If you have not saved the configuration during this lab simply reload your routers. NOTE: If prompted to save the configuration say no. 2. If you did save, issue the command erase startup-config, then reload the router. After the router reboots, paste in your base config in global config mode.
