Task 1: Design and document an addressing scheme.
Step 1: Design an addressing scheme.
Based on the network requirements shown in the topology, design an appropriate addressing scheme.
• Address the LANs in order starting with LAN 1, then LAN 2, etc. Use the first address for the
router interface and the last address for the PC.
• The addressing requirements for the LANs are:
o Router B1 interface Fa0/0 supports 60 hosts.
o Router B1 interface Fa0/1 supports 60 hosts.
o Router B2 interface Fa0/0 supports 30 hosts.
o Router B2 interface Fa0/1 supports 30 hosts.
o Router B3 interface Fa0/0 supports 10 hosts.
o Router B3 interface Fa0/1 supports 10 hosts.
o Router HQ interface Fa0/0 supports 5 hosts.
o Router HQ interface Fa0/1 supports 5 hosts.
• Address the WANs in order starting with WAN 1, then WAN 2, etc. HQ is the first usable address
in all WAN links, with the exception of the link to ISP. For the ISP link, HQ uses the second
usable address.
o WAN 1 is the link between HQ and B1.
o WAN 2 is the link between HQ and B2.
o WAN 3 is the link between HQ and B3.
Step 2: Document the addressing scheme.
• Record the network addresses in dotted-decimal/slash format.
• Document the IP addresses, subnet masks and default gateway addresses.
