Figure 1-6 Addressing Design Exercise 4 Topology
Address Space
10.10.96.0/21
10.10.102.0/24
250 Hosts
10.10.103.248/30
List the address space that is still available for future expansion.
For the solution shown in Figure 1-6, the address space still available is .103.252/30; .103.224/28;
.103.192/27; .103.128/26; .103.0/25.
VLSM Addressing Design Scenarios
The following VLSM Addressing Design Scenarios will build upon your addressing design skills. In these
scenarios, you will fully document your network design, including IP addresses for interfaces and hosts.
Instructor Note: Once students have successfully completed a scenario, have them test it out on real routers or a simulator
such as Packet Tracer.
VLSM Addressing Design Scenario 1
Complete Addressing Design Scenario 1 using the following list of requirements:
■ Address space: 192.168.1.0/25.
10.10.96.0/22
1,000 Hosts
RTA
RTC RTB
10.10.103.244/30
■ RTA LAN, 60 hosts; RTB LAN, 30 hosts; RTC LAN, 10 hosts.
■ Using good VLSM design practices, contiguously assign subnets to the topology shown in Figure 1-7.
■ 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.
10.10.103.240/30
10.10.100.0/23
500 Hosts
