The gateway of last resort is now set as 161.44.192.2. If you configure ip default-network 198.10.1.0, the routing table changes to this: 2513# show ip route Note the static route to 198.10.1.0 via 161.44.192.2 and that the gateway of last resort is not set.

When you configure ip default-network the router considers routes to that network for installation as the gateway of last resort on the router.įor every network configured with ip default-network, if a router has a route to that network, that route is flagged as a candidate default route. Unlike the ip default-gateway command, you can use ip default-network when ip routing is enabled on the Cisco router. This example defines the router on IP address 172.16.15.4 as the default route: ip default-gateway 172.16.15.4 ip default-network In boot mode, the router does not have ip routing enabled.

You might also use this command when your low end Cisco router is in boot mode in order to TFTP a Cisco IOS® Software image to the router.

It should only be used when ip routing is disabled on the Cisco router.įor instance, if the router is a host in the IP world, you can use this command to define a default gateway for it. The ip default-gateway command differs from the other two commands. Conventionsįor more information on document conventions, see the Cisco Technical Tips Conventions. If you are working in a live network, ensure that you understand the potential impact of any command before using it. All of the devices used in this document started with a cleared (default) configuration. The information presented in this document was created from devices in a specific lab environment. The command outputs shown are from the Cisco 2500 Series routers running Cisco IOS ® Software Release 12.2(24a). This document is not restricted to specific software and hardware versions. There are no specific requirements for this document.

Default routes are invaluable in topologies where learning all the more specific networks is not desirable, as in case of stub networks, or not feasible due to limited system resources such as memory and processing power. Be careful not to copy the quotation signs.Default routes are used to direct packets addressed to networks not explicitly listed in the routing table. Step2: Copy and paste the command below into the terminal and hit the enter key: “wget ”. Hit the enter key a couple of time and using the down arrow key, navigate to the shell option and hit the enter key. Step1: Ssh to the IP address of your gns3vm using putty or any other terminal emulation software.

I am assuming that your gns3 is installed and linked to the gns3 VMware and that your Cisco IOU L2 image has been download and successfully imported into the Cisco IOU L2 appliance.Īt this point, an attempt to run the appliance without the license key, you will get an error that says “Could not find an iourc file (IOU license), please configure an IOU license” To get rid of this error, follow the steps below.

In this post, I will share four easy steps to generate and install the Cisco IOU L2 keygen license for use in gns3.
