have a route to

Part (e)

You design a secure network for a customer who wants the same subnet mask on every
subnet. The customer will use network and needs 200 subnets, each with 200
hosts maximum. What subnet mask would you use to allow the most growth in subnets?
Which mask would work and would allow for the most growth in the number of hosts per

Create a configuration for IGRP on a router with these interfaces and addresses: to0 using, e0 using, s0 using, and s1 using
