Learning by Doing: CISCO Certified Network ... - SCN Research

Supplemental Lab or Challenge Activity:
1. You are the network administrator for a small real estate company in Tulsa,
Oklahoma. You have to set up a network with two CISCO 2611 routers, 4 1924
switches, and18 workstations and 4 printers per subnet. For security purposes you have
decided that you do not want to advertise subnet information for one subnet on each
router. Therefore you have decided to use discontiguous subnets so your routers will
summarize routes. You will need to design and set up 4 subnets in the company. When
you are finished designing it you will need to build it and be able to ping from each
workstation to each other workstations where possible.
2. A good command to remember is to use is clear ip route *. Sometimes you want to
force your IP table to update and change and this is one good way to make that happen.
3. Let’s look at some designs and have you determine whether all workstations could
ping all other workstations before implementing it. In other words do you think that
given the IP addressing design that the routers will summarize the networks or not?
