VLSM Addressing Design Scenario 6
Complete Addressing Design Scenario 6 using the following list of requirements:
■ Address space: 10.0.0.0/15.
■ RTA LAN, 65,000 hosts; RTB LAN, 30,000 hosts; RTC LAN, 8000 hosts.
■ Using good VLSM design practices, contiguously assign subnets to the topology shown in Figure 1-12.
■ Fill in the table with all necessary IP address configuration information for all devices. Use dotteddecimal
format for the subnet mask.
■ List the address space that is still available for future expansion.
