For the solution shown in Figure 6-11, the address space still available is 116.12/30, .116.16/28,
.116.32/27, .116.64/26, .116.128/25, .117.0/24, .118.0/23, and .120.0/21.
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 6-12.
