NETW-204 Assignment #3
Refering to figure 1 below: You are the network administrator for the network depicted in the diagram. You have been assigned the address space 10.1.16.0/21 to create the LANs you need, and the 172.16.1.0/28 space for your WAN links.
LAN: 10.1.16.0/21WAN: 172.16.1.0/28 |
Begin by creating and assigning the LAN subnets you will use. In order to make the most efficient use of your address space you should start by creating the subnet needed for the LAN with the most hosts and then work you down to the smallest LAN.
Using the address space 10.1.16.0/21, create subnets for the LANs shown in the diagram and fill in the table 1 below. ...view middle of the document...
Assign the first IP address for all LANs to the router interface.
2. Assign HQ the first IP address for all WAN links to Branch routers.
