Great.
So now let's get to know.
Three closely.
It closed at the moment, so I'll go to the applications menu and run three by clicking on its icon.
The project window appears at the beginning so you can create a new project or click the Projects Library
tab to open an existing project.
Here's a project we created in the previous lecture, so select that and click okay to open it.
We haven't worked on it yet, so we have nothing on the workspace.
The large window is called the workspace, and this is where your various routers switches and things
like that are going to be connected to each other.
So this is where you're going to create your topology.
All right.
So at the left hand side of the app, we have a toolbar called the Devices Toolbar.
Aptly enough, now it shows you all of the nodes that are available.
So if I click on this one.
This shows me all of the router nodes that are available.
If installed and available appliances is the option selected in the combo box above.
You'll see all the available options in the list.
Here you see the installed nodes.
Boulder and the nodes not installed yet are grayed out.
The second icon shows the switching nodes that are available.
Again, the nodes ready to use are in bold and there are switches embedded in the Gns3 app and those
are ready to use.
Here's the Ethernet switch router that we created in the previous lecture.
Now, the third one lists end devices such as virtual PC nodes or a cloud node.
If you select installed appliances from the combo box, you'll see the nodes that you can use at this
very moment.
If the node you want to use is not listed here, you've got to install it first.
Now, perhaps you remember we installed a router C 3725 and it's available now.
There are some nodes installed and available by default, such as this vpcs and cloud.
Now, the fourth menu option lists the security devices.
No security device installed by default.
The fifth menu item shows all the nodes together routers, switches and devices.
ET cetera.
The last menu item adds nodes to each other, so pretty much anything that you can drag and drop into
this working area right here is what the Gns3 considers to be a node, whether it be a router, a switch,
a PC or a firewall.
They all are considered as nodes from the gns3 standpoint.
