You are the network administration for the small network in Figure 2. It consists of your headquarters location with a LAN with 60 hosts, remote office R1 with 10 hosts, and remote office R2 with 30 hosts. You have been assigned the address space 192.168.3.0/25. From this space you will need to create the subnets for each of the sites on your network and the two WAN links. Once you find the subnets assign addresses to the Routers interfaces and PCs using the following guidelines: Assign the first address from LAN subnets to the router interface connected to that LAN. Assign the second IP address in the LAN subnet to the PC on the LAN. Assign the first Address from WAN subnets to the HQ router end of the WAN link and the second address to the remote router interface. Use the steps below to help you work through it. Create the subnets: Address space: 192.168.3.0/25 Write it out in binary form identifying the host and network then use the space below in table as a scratch pad to help you in subnetting as needed. Remember to be efficient you usually want to start by creating the largest subnet you need first and then continue subnetting to find the smaller subnets in succession. Subnet Table Question Answer 23 What is the HQ subnet (address/mask)? 24 What is the R1 subnet (address/mask)? 25 What is the R2 subnet (address/mask)? 26 What is the subnet for the HQ to R1 WAN (address/mask)? 27 What is the subnet for the HQ to R2 WAN (address/mask)? Fill in the address and subnet mask for the device interfaces in the table below using the assignment rules described above. Device Interface Address Mask HQ Router Fa0/0 28 39 S0/0/0 29 40 S0/0/1 30 41 R1 Router Fa0/0 31 42 S0/0/0 33 43 R2 Router Fa0/1 34 44 S0/0/0 35 45 PC1 Ethernet 36 PC2 Ethernet 37 PC5 Ethernet 38 What subnets do you have left available for future use? 46. 47. PC’s on a LAN need to have a default gateway configured that identifies the next hop IP address for packets leaving the network. This is the address of the router interface on the LAN. Based on this what address will be assigned as the default gateway on the following PCs. 48. PC1 = 49. PC2 = 50. PC5 =
