Use a Fiber cable to connect the FastEthernet4/0 port on Router2 to the FastEthernet6/0 port on Router 3. Now you're ready to calculate the subnets you'll use in your Packet Tracer network. Answer the following questions: 7. You'll need a different subnet for each connection to a router or each connection between routers. How many subnets will you need altogether? 8. Using the formula 2 - Y, how many bits will you need to borrow from the host portion of the IP address? 9. What will your new subnet mask be? 10. What is the magic number for these calculations? 11. How many possible hosts can each subnet have? 12. Fill in the Network ID column in Table 8-12 with the first several subnets for this network. The first one is filled in for you. The table only covers the subnets you'll need for this project. 13. Fill in the Broadcast address column in Table 8-12. 14.

Let's take the first subnet here and divide it again into three additional, smaller sub nets. Answer the following questions: 15. If you borrow one more bit from the host portion of the IP address in Subnet 1. how many smaller subnets will this create? Is this enough? 16. If you borrow two more bits from the host portion of the IP address in Subnet 1, how many smaller subnets will this create? Is this enough? 17. What's the new subnet mask for these smaller subnets? 18. How many hosts can each of these smaller subnets have? 19. Filin Table 8-13 with the smaller subnets' information. The first one is filled in for you.

Complete the following steps: 20. Each of the smaller subnets will be assigned to a connection between two routers. Each router interface will be assigned a host IP address within that smaller subnet. Notice in Table 8-14 how the IP addresses for these smaller subnets are assigned to each routers interfaces (Fa4/0 for Routers 0, 1, and 2, and all three interfaces for Router 3). 485 W Phy the media her e grandstander R The r et Ethernet interface for e dortmany e al theme work modules de offertes 10/100 or 100 Ethernet cloure 8-36 Add a new Fast-Ethernet interface for fiber media to the router Source: Cisco Systems, Inc 6.
