■ Configure routers with basic configurations using your addressing scheme.
■ Configure dynamic, static, and default routing.
■ Verify connectivity and troubleshoot problems.
Equipment
The topology shown in Figure 1-37 uses 2600 series routers. This lab can be done with any combination of
1700, 2500, and 2600 series routers.
NetLab Compatibility Notes
This lab can be completed on a standard NetLab three router pod.
Task 1: Design the Addressing Scheme
You are given the address space, 10.1.0.0/20. The loopback interfaces on RTA and RTB are used to simulate
different areas of the network. Although each loopback interface could be one LAN or a group of
LANs summarized in one routing update, this discussion simply refers to each loopback interface as a simulated
LAN.
Design an addressing scheme by following these requirements:
Step 1. RTA and RTB will share the 10.1.0.0/20 address space equally. Split the address space into two
equal subnets. Record your subnets with prefix notation in the space provided.
10.1.8.0/21 10.1.0.0/21
