Task 1: Design and Document an Addressing Scheme
Design an addressing scheme.
Step 1.
Based on the network requirements shown in the topology in Figure 9-13, design an
appropriate addressing scheme.
For the LANs, use the address space 10.1.32.0/22. Starting with the largest subnets'
requirements on B1, assign subnets in order throughout the topology.
■
For the WANs, use the address space 172.20.0.0/27. Assign WAN subnets according to
the following specifications:
■
Subnet 0 to the WAN link between HQ and B1
■
Subnet 1 to the WAN link between HQ and B2
■
Subnet 2 to the WAN link between HQ and B3
■
Subnet 3 to the WAN link between B1 and B2
■
Subnet 4 to the WAN link between B2 and B3
■
Document the addressing scheme.
Step 2.
Use the blank spaces on the topology to record the network addresses in dotted deci-
mal/slash format.
■
Use Table 9-9 to document the IP addresses, subnet masks, and default gateway
addresses:
■
For LANs, assign the first address to the router interface. Assign the last address to
the PC.
■
For WAN links to HQ, assign the first address to the HQ router.
■
For WAN links between branch routers:
■
Assign the first address to B1 for the link between B1 and B2.
Assign the first address to B2 for the link between B2 and B3.
Task 2: Apply a Basic Configuration
Configure the routers.
Step 1.
Using your documentation, configure the routers with basic configurations.
Configure the PCs.
Step 2.
Using your documentation, configure the PCs with an IP address, subnet mask, and default
gateway.
Task 3: Test Connectivity
Before continuing, make sure that each device can ping its directly connected neighbor.
