Apr 10, GNS3 is a network simulator software used by hundreds of thousands of network engineers worldwide to emulate, configure, test and troubleshoot virtual and real networks. GNS3 can talk a large number of network vendors including MikroTik. GNS3 is the best friend for those who are unable to arrange a lot of real devices and fail to configure, test and troubleshoot any complex network with MikroTik Router.

Now it is time to configure and test our integrated MikroTik Router by designing and configuring a basic network on GNS3. In this article, we will configure a basic network that looks like to the below image. If you face any difficulty to design this network on GNS3, feel free to visit my previous article about GNS3 installation and configuration where I have discussed how to design networks on GNS3.

In the above network diagram, there are five network appliances. Among these Ethernet Switch is a plug and play device. So, there is no configuration for LAN Switch. So, it has to connect to any real network adapter. Click mouse Right Button on the cloud icon and click on Configure option. Node properties window will appear.

Inside this window, click on Ethernet interfaces tab. Inside Ethernet interfaces tab, choose your desired network adapter that you want to bind with this Cloud from dropdown menu and then click on Add button. Your added network adapter will be listed in the Ethernet interfaces box area. Now click Apply and OK button. We will just do some basic configurations in MikroTik Router. The following steps will show how to perform these tasks on MikroTik Router.

MikroTik Router has been completed. MikroTik Router is now ready to communicate with the public network.By dragging one in from the End devices pane. But there are other commands worth checking out like:. Use set dump off to turn it off. But there is another way of using the Virtual PC Simulator that gives you even more options — you may have seen it on your Tools menu.

VPCS multi-host. To set up a VPCS multi-host, drag either a cloud or host device onto your topology. Next, select the device, and choose Device Configure. This brings up the Node Configurator hopefully soon this will change name to the Properties dialogue. Initially, the settings should be just perfect for VPCS[1] — with the Local port setting atthe Remote host set to For the second VPCS host, you need to use ports and And for the third VPCS host, ports and and so on. You can configure up to nine VPCS hosts in this way.

No matter how many VPCS multi-host you configured, only one window opens — and the prompt is slightly different; it will show:. With VPCS multi-host you can load a script file that tests your configuration from multiple points. There is no easier way to explain this than to show you a script checking one of my GNS3 WorkBench exercises. So the choice is yours — use either the regular Single instance VPCS, or configure your hosts to run in a single VPCS multi-host instance — you might even get adventurous and start writing your own scripts.

One device will be selected as the primary device, and the other will be the secondary device.

The vPC peer link carries control traffic between two vPC switches and also multicast, broadcast data traffic. In some link failure scenarios, it also carries unicast traffic. You should have at least two 10 Gigabit Ethernet interfaces for peer links. It is also associated with the configuration mode that you must use to assign vPC global parameters.

The peer keepalive link sends periodic keepalive messages between vPC peer devices. No data or synchronization traffic moves over the vPC peer keepalive link; the only traffic on this link is a message that indicates that the originating switch is operating and running vPC.

Figure 3. Table 1. Step 1. Enter the global configuration mode. Step 2. Enable the vPC feature. The vPC feature must be enabled before it can be configured. Step 3. Create a vPC domain and assign a domain ID.

Step 4. Management interface for peer keepalive link:. SVI for peer keepalive link:. Configure the IPv4 address for the remote end of the vPC peer keepalive link. The system does not create the vPC peer link until you configure a vPC peer keepalive link. Two VRF instances are created when the system boots: management and default. Both management interfaces and SVIs can be used for peer keepalive links.

The management interface and VRF management instance are the defaults. The second example shows how to configure the SVI as the keepalive link. The source address must be specified when the VRF default instance is used for peer keepalive communication. Step 5.

Optional Enter the system priority that you want for the specified vPC domain. The range of values is 1 to The default value is When you manually configure the system priority, make sure that you configure the same priority value on both vPC peer devices.

If these values do not match, vPC will not be activated. Step 6. Optional Enter the role priority that you want for this vPC switch. The range of values is 1 toand the default value is The switch with lower priority will be elected as the vPC primary switch.

If the peer link fails, vPC peer will detect whether the peer switch is alive through the vPC peer keepalive link. If the vPC primary switch is alive, the vPC secondary switch will suspend its vPC member ports to prevent potential looping while the vPC primary switch keeps all its vPC member ports active.You may find much of the following out of date.

VPCs Tutorial

Click on this link to be taken to the new tutorial]. Technical note: This tutorial was written using VPCs version 0. If you are not working with the GNS3 Workbenchthen download the topology, config and startup. Or of course, you could just build your own network based on the diagram below. After all the routers have started, and the routing protocol converged, you are ready to start learning about VPCs.

The [1] shows that your focus is Virtual PC 1. It helps if you understand that the reason that your VPCs have any configuration is because there is a startup file that serves as a script file when you run vpcs.

You will learn more about script fiels in Lesson 7, but for now, I want you to understand that your startup. Now continue by pinging the default gateway The arp entry is OK.

When you ping a remote device, often the first ping times out if a router along the way has go through an arp request. This can be done with any command, so long as you type enough to identify the command. If you press the up-arrow then down-arrow keys, you will see that you can recall your previous commands.

You can further edit these commands using the left-arrow and right-arrow keys. The command? Your history is kept from session to session. If you quit a VPCs session, it saves the current command history in a file called vpcs.

To access one of the other VPCs, type a digit on a line by itself. In the example below, notice how I enter 2 to move to PC2, and then use the up-arrow to retrieve the ping command. Notice that the first ping says that the local IP See how this is different to the second ping, which would have been sent all the way to Yosemite router, and of course Yosemite would not have been able to reach the non-existant For the third ping to 4.

To explore the many other ICMP replies you might get, you will first have to change some of the routing tables on these routers to make them think the network is different to what it physically is. In summary, you will:. This lesson shows you how to interpret a variety of ICMP replies and options. In particular you will explore:. Note how the pings went to Seville, and Seville Issue a ping command by itself to see the ping options.

You will:. To do this you will:. What a great tool to test ACLs!! I could have said ping However, if you send a UDP packet to a device that is not listening on a particular port, the target device sends back am ICMP type:3, code:3 — Destination Port unreachable. Tracert actually uses the fact that routers send ICMP destination unreachable messages to trace the path through a network.

In this lesson, you will:. Note that the default gateway router Albuquerque did actually reply to the first round of packets sent with a TTL of 1, proving that routers actually make the routing decision before they decrement the TTL.
