Page 1 of 7 Lab Designing and Implementing a VLSM Addressing Scheme Topology Objectives Part 1: Examine Network Requirements Part 2: Design the VLSM Address Scheme Part 3: Cable and Configure the IPv4 Network Background / Scenario Variable Length Subnet Mask (VLSM) was designed to avoid wasting IP addresses. With VLSM, a network is subnetted and then re-subnetted. This process can be repeated multiple times to create subnets of various sizes based on the number of hosts required in each subnet. Effective use of VLSM requires address planning. In this lab, use the 172.16.128.0/17 network address to develop an address scheme for the network displayed in the topology diagram. VLSM is used to meet the IPv4 addressing requirements. After you have designed the VLSM address scheme, you will configure the interfaces on the routers with the appropriate IP address information. 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). Other routers 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 have been erased and have no startup configurations. If you are unsure, contact your instructor. Required Resources 3 routers (Cisco 1941 with Cisco IOS software, Release 15.2(4)M3 universal image or comparable) 1 PC (with terminal emulation program, such as Tera Term, to configure routers) Console cable to configure the Cisco IOS devices via the console ports Ethernet (optional) and serial cables, as shown in the topology
