    Book of GNS3

    Build Virtual Network Labs Using Cisco, Juniper, and More by Jason C. Neumann May 2015, 296 pp. ISBN: 978-1-59327-554-9 GNS3 is open source software that uses emulated router and switch hardware on Windows, OS X, and Linux to create a real world environment of complex networks. You can use GNS3 to experiment with new network features or to verify configurations for later deployment on real devices, making it an excellent tool for network engineers, administrators, and anyone studying for Cisco or Juniper certifications. The Book of GNS3 teaches you to harness this tool to build and test your own network labs. You’ll learn to use GNS3 by following tutorial-based explanations, and each chapter introduces new concepts that build on skills from previous ones. Discover how to create and manage simple to complex networks in GNS3, using only a single computer or balancing the load across multiple computers, and stop reconfiguring your physical hardware every time you want to test something new. About the Author Jason C. Neumann is an active participant in the GNS3 project, supplying code, moderating forums, and beta testing the software on several platforms. He holds numerous network-related certifications, was one of the first Certified Novell Engineers in the United States, and has been Cisco-certified since 1999. He is the author of Cisco Routers for the Small Business (Apress). Table of Contents Introduction Chapter 1: What is GNS3? Chapter 2: Installing a Basic GNS3 System Chapter 3: Configuration Chapter 4: Creating and Managing Projects Chapter 5: Integrating Hosts and Using Wireshark Chapter 6: Juniper Olive and vSRX Firefly Chapter 7: Device Nodes, Live Switches, and the Internet Chapter 8: Cisco ASA, IDS, and IOS-XRv Chapter 9: Cisco IOS on Unix and NX-OSv Chapter 10: Cool Things to Do on a Rainy Day Chapter 11: Help!

  3. EIGRP Simulation After adding Interior router, no routing updates are being exchanged between Perimeter and the new location. All other inter connectivity and Internet access for the existing locations of the company are working properly. The Task is to identify the fault(s) and correct the router configurations to provide full connectivity between the routers. Access to the router CLI can be gained by clicking on the appropriate host. All passwords on all routers are cisco. IP Address are listed in the chart below [Hidden Content] Steps Remove invalid Autonomous System Number and add the correct Autonomous System Number Interior router. The Autonomous System Number is found in the topology: Add the network address of Fa0/0 interface of Perimeter router in EIGRP configuration. Because EIGRP neighbor relationship is not possible without the configuring connected interfaces. Answer Commands First we should check the configuration of the Interior Router. Click the console PC “F” and enter the following commands. Interior> enable Password: cisco Interior# show running-config Building configuration... Current configuration : 770 bytes ! version 12.2 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname Interior ! enable secret 5 $1$mERr$hx5rVt7rPNoS4wqbXKX7m0 ! interface FastEthernet0/0 ip address 192.168.77.34 255.255.255.252 duplex auto speed auto ! interface FastEthernet0/1 ip address 192.168.60.65 255.255.255.240 duplex auto speed auto ! interface FastEthernet1/0 ip address 192.168.60.81 255.255.255.240 duplex auto speed auto ! router eigrp 22 network 192.168.77.0 network 192.168.60.0 no auto-summary ! ip classless ! line con 0 line vty 0 4 login ! end Interior# From the output above, we know that this router was wrongly configured with an autonomous number (AS) of 22. When the AS numbers among routers are mismatched, no adjacency is formed. (You should check the AS numbers on other routers for sure) To solve this problem, we simply re-configure router Interior router with the following commands: Interior# conf t Interior(config)# no router eigrp 22 Interior(config)# router eigrp 222 Interior(config-router)# network 192.168.60.0 Interior(config-router)# network 192.168.77.0 Interior(config-router)# no auto-summary Interior(config-router)# end Interior# copy running-config startup-config Second we should check the configuration of the Perimeter Router. Click the console PC “G” and enter the following commands. Perimeter> enable Password: cisco Perimeter# show running-config Building configuration... Current configuration : 1029 bytes ! version 12.2 no service timestamps log datetime msec no service timestamps debug datetime msec no service password-encryption ! hostname Perimeter ! enable secret 5 $1$mERr$hx5rVt7rPNoS4wqbXKX7m0 ! interface FastEthernet0/0 ip address 192.168.77.33 255.255.255.252 duplex auto speed auto ! interface Serial0/0 ip address 192.168.36.13 255.255.255.252 clock rate 64000 ! interface Serial0/1 ip address 192.168.60.25 255.255.255.252 clock rate 64000 ! interface Serial1/0 ip address 198.0.18.6 255.255.255.252 ! interface Serial1/1 no ip address shutdown ! interface Serial1/2 no ip address shutdown ! interface Serial1/3 no ip address shutdown ! router eigrp 222 network 192.168.36.0 network 192.168.60.0 network 192.168.85.0 network 198.0.18.0 no auto-summary ! ip classless ip route 0.0.0.0 0.0.0.0 198.0.18.5 ! line con 0 line vty 0 4 login ! end Perimeter# Notice that it is missing a definition to the network Interior. Therefore we have to add it so that it can recognize Interior router Perimeter# conf t Perimeter(config)# router eigrp 222 Perimeter(config-router)# network 192.168.77.0 Perimeter(config-router)# end Perimeter# copy running-config startup-config Now the whole network will work well. You should check again with ping command from router Interior to other routers!

All other inter connectivity for the existing locations of the company are working properly. But Internet connection for existing location including Remote1 and Remote2 networks are not working. Faults Identified: 1. Incorrect Autonomous System Number configured in Interior router. 2. Perimeter router does not advertise route to the new router Interior. 3. Internet Connection is not working all stations. We need to correct the above two configuration mistakes to have full connectivity Steps: 1. Interior Router: Change the Autonomous System Number of Interior 2. Perimiter Router: Add the network address of interface of Permiter that link between Perimeter and Interior. 3. Perimiter Router: Add default route and default-network. Check the IP Address of S1/0 interface of Perimeter Router using show running-config command. (The interfaced used to connect to the ISP)! interface Serial1/0 ip address 198.0.18.6 255.255.255.252 ! For Internet sharing we have create a default route, and add default-network configuration. The IP address is 198.0.18.6/30. Then the next hop IP will be 198.0.18.5. Interior Router Interior>enable Password: cisco Interior# conf t Interior(config)# no router eigrp 22 Interior(config)# router eigrp 222 Interior(config-router)# network 192.168.60.0 Interior(config-router)# network 192.168.77.0 Interior(config-router)# no auto-summary Interior(config-router)# end Interior# copy running-config startup-config Perimeter RouterPerimeter>enable Password: cisco Perimeter# conf t Perimeter(config)# router eigrp 222 Perimeter(config-router)# network 192.168.77.0 Perimeter(config-router)# exit Perimeter(config)# ip route 0.0.0.0 0.0.0.0 198.0.18.5 Perimeter(config)# ip default-network 198.0.18.0 Perimeter(config)# exit Perimeter# copy running-config startup-config Important: If you refer the topology and IP chart, the Perimeter router uses Fa0/0 to connect Interior router, S0/0 used to connect Remote1, and S0/1 used to connect Remote2. Refer to the command show running-config, the command #PASSIVE-INTERFACE <Interface Name> will deny EIGRP updates to specified interface. In that case we need to use #no passive-interface <Interface Name> to allow the routing updates to be passed to that interface. For example when used the #show run command and we see the output like below.! router eigrp 22 network 192.168.77.0 network 192.168.60.0 passive-interface FastEthernet 0/0 passive-interface Serial 1/0 no auto-summary ! Then the command would be Perimeter(config)#router eigrp 222 Perimeter(config-router)#no passive-interface Fa0/0 Perimeter(config-router)#end Also Perimeter router connect to the ISP router using Serial 1/0. If you seen passive-interface s1/0, then do not remove it using #no passive-interface s1/0 command. Download Lab file (requires packet tracer) [Hidden Content] [Hidden Content]
