14 Switching Basics and Intermediate Routing CCNA 3 Labs and Study Guide
List the address space that is still available for future expansion.
For the solution shown in Figure 1-2, address space still available is .60/30; .64/26; .128/25.
The topology shown in Figure 1-3 has LAN subnets already assigned out of the 192.168.1.0/24 address
space. Using VLSM, create and label the WANs with subnets from the remaining address space.

List the address space that is still available for future expansion.
Answers may vary. In the answer shown in Figure 1-3, the available address space is .172/30; .176/28;
.192/26.

Your address space is 192.168.1.192/26. Each LAN needs to support ten hosts. Use VLSM to create a contiguous
IP addressing scheme. Label Figure 1-4 with your addressing scheme. Don’t forget the WAN links.
