Now that you know the benefit of VLSM, take a look at how you can use it in a network.

Answers A and B are incorrect: By decreasing the total number of IP addresses. See All Related Store Items.

When designing a network using VLSM, the ccba simple steps can help come up with an appropriate addressing scheme:. Answer C is correct.

Only the accounting dept can use FTP files to the server at the central office The IP address assigned to the company is They have 4 remote sites, 3 of which run a single subnet with 10, 20 and 27 hosts respectively while the 4th site has 50 hosts, divided amongst 3 Ethernet networks as follows: For example in Figurefor the networks connected to RouterB and RouterC, a block size of 32 was used even though the total addresses required were 21 in each subnet.

It is simply the application of different subnet masks within a routed system. Label all ports with the relevant IP address and subnet mask in the following table. Each remote site connects to the central office with a T1 leased line running at ccma. Because it allows each subnet in a routed system to be correctly sized for the requirement. It is impossible to subnet a subnet. There are cfna few restrictions you need to consider when planning to use VLSM: Classful protocols such as RIPv1 do not include the subnet mask of advertised networks in their routing updates; therefore, they cannot possibly learn the existence of more than one mask length.

What must a routing protocol be able to do to support VLSM? This workbook walks you through over fkletype examples to help you really understand the ins and outs of subnetting. Answer A is not a requirement.

Sales — 30 hosts, Accounting — 10 hosts and servers — ffiletype hosts. Classless protocols on the other hand advertise and understand subnet masks. By decreasing the total number riletype IP addresses C. Home Guides About Blog Fileype. VLSM allows you to use different subnet masks across the network for the same class of addresses.

By creating subnets D. The branches are connected to the central office via point-to-point WAN links.

The problem arises when the routing protocols are configured: No hosts in either sales or accounting can telnet to the central office router 4. Draw a logical diagram of the network, labelling all devices and ports. The central office has 60 hosts this includes a number of servers, one of which is used to store data from the accounting department on Router4.

In simulation mode, create a scenario and send a packet from Router 3 to Router 1 and a packet from router2 to the central office NB: You will notice that in every subnet except the subnet attached to RouterD, some host addresses will remain unused.

Multicast Automatically summarize networks to a common mask Advertise the mask for each subnet in the routing update Answers Answer D is correct.

Consider the example shown in Figure and work through the above steps to see how the network address and v,sm mask was found for each segment:. No internet traffic to access the payroll server on Router4 2. The largest subnet requires 30 host addresses. Page 2 of 4 Highlight all, Copy the configuration and paste into a notepad file.

Answer D is correct. It is not only possible, you can in fact subnet a subnet of a subnet—and keep going as long as there are sufficient bits left in the mask.

You need to use fixed block sizes. Summarise the IP addresses and subnet masks in a table. No hosts in the sales network on Router4 can access the payroll server on Router4 3.
