Introduction

Assignment

Develop a subnetting plan and implement it in the lab. Configure RIP as a routing protocol.

Conditions

NYEDGE1 is the hub router. The two remote office routers NYEDGE2 and NYWAN1 connect to NYEDGE1 through serial connections. Each router has a locally attached Ethernet network. The serial line data rates and DTE/DCE settings have already been configured on all three routers. You only need to assign the IP address to the interfaces.

Notes

The routers are connected directly to each other in this lab and do not actually connect through any leased line services.

Task 1 - Create a subnet plan

How many segments and users/segment do you need to accommodate?

Step 1: Determine the correct subnet mask.

Action: Develop a subnet plan based on the story and conditions. Result: A three bit mask creates 6 usable subnets. Explanation: Because you were instructed to use only one major network, you must design a subnet plan based on the number of users per segment and the number of segments that must be addressed. In this configuration, there are 5 segments which need to be addressed: three Ethernet interfaces and two serial lines. So you must use a subnetting scheme which provides at least five subnets. Using two subnet bits (192) creates two usable subnets, three subnet bits (224) creates 6 usable subnets, four bits (240) creates 14, etc. Therefore at least three bits must be used. That means subnet masks 224, 240, 248, 252 are all candidates for subnet masks. However, you need to select a mask that will support the number of...
