How to Route Protocol Layers

There are two route protocol layers called three and four. These numbers come from the OSI model (open systems interconnect). In the OSI model, there are seven layers but only layers three and four are used for routing. Layer three is routing protocol and layer four is a routable protocol. For easier understanding, compare it to the Post Office system; one is a mail envelope and the other is a Post Office. The mail envelope has a source and destination address, whereas the post office can route the mail to any location.

1. First: Set-up static IP address

   Set up static IP address

   Set up an IP (Internet Protocol) address on a server or on a router. The IP address is a routable protocol and it is a layer three protocol from the OSI network model.

2. Second: Configure routable protocol

   Click "Start" on the Windows screen and then click "Control panel." Select the "Network and Internet" icon and then "Network and Sharing Center." Click the "Local Area Connection" icon and then click "Properties." Click the "TCP/IPv4" option. Now, configure the IP address with the numbers "192 168 250 1." Configure the Subnet mask with "255 255 255 0." Click "OK" and "Close." This completes the configuration for a routable protocol. Now the PC appears on the network.

3. Third: Set-up a routing protocol

   Type the command "Enable" on the router screen. Next type "Configure terminal" to enter privileged mode. In the router, you set up a routing protocol, which is layer four on the OSI model. This takes the IP number and routes it to other networks. You need a routing protocol, like RIP (Routing Information Protocol).

4. Fourth: Identify version of RIP

   Type "Router Rip" to create a routing protocol. Next, type the command "version 2." This identifies the version of RIP. The next command is "network 172 69 17 0." This is the network address that you want to circulate throughout the network.
