Using a Router that acts Like a PC

By arfs -
You may also simply add another router to your topology and configure it to act like a PC. This method would use more memory and processor cycles than the previous method, so I would only recommend this method as a secondary choice.
Just add a router and enter the following commands:

Router(config)# no ip routing (Turns off IP routing function )
Router(config)# interface fa0/0 (Switches to FastEthernet interface)
Router(config-if)# ip address address subnet_mask (Assigns IP address and subnet mask to interface )
Router(config-if)# no shutdown (Turns interface on )
Router(config-if)# exit (Returns to global configuration mode )
Router(config)# ip default-gateway (gateway_address Configures the default gateway )
Router(config)# ip http server (Optional – starts http server process Connect the router (acting as a PC) to the rest of your topology.)

Examining the DR/BDR Election Process

Routers Used : 3640 w/ NM-1FE-TX IOS : c3640-jk9s-mz.124-16a Objective : In this lab, observe the OSPF DR and BDR election processing using debug commands. Then assign each OSPF interface a priority value to force the election of a specific router as a DR. Scenario The backbone of International Travel Agency’s enterprise network consists of three routers connected using an Ethernet core. Asterix1 has more memory and processing power than the other core routers. Unfortunately, other core routers are continually elected as the DR under the default settings. In the interest of optimization, ensure that Asterix1 is elected the DR, because it is best suited to handle associated extra duties, including management of Link State Advertisements (LSA) for Area 0. Investigate and correct this situation. Step 1 Build and configure the network according to the diagram. Use the configuration files from the previous lab if available . Configure OSPF on all Ethernet interfaces. A switch or hub is req

Cisco binary image unpacker is a software that allows you to unpack the IOS and ASA images. Follow this steps to use this software for GNS3. With this way the Router loading process can be faster. This is useful for those of you that do start and stop Router frequently. Donwload Cisco image unpacker 0.1  for Windows. Extract thi zip file to your specific folder.. Copy the IOS file to this folder, for example "c3640-jk9s-mz.124-16a.bin". On windows command prompt, type the following command: "unpack c3640-jk9s-mz.124-16a.bin" (without ""). The output file stored in temporary folder, in my case "C:\Documents and Settings\dion\Local Settings\Temp". Open the folder and you will find the unpacked file "C3640-JK.bin", file size is about twofold. Copy "C3640-JK.bin" to your IOS folder. Your can also rename the file to "c3640-jk9s-mz.124-16a(unpacked).bin" Open GNS3, On the Edit menu, choose IOS image and hyper
