RIP Advanced

Written by Rene Molenaar on . Posted in RIP

Scenario:

You are a freelance network engineer and one of your customers has an old network based on the RIP routing protocol. This networks needs some tuning so it's time to use some more advanced RIP tricks.

Goal:

  • All IP addresses are preconfigured as specified in the topology picture.
  • Configure RIP version 2 on all routers, make sure it does no summarization by itself.
  • Advertise all networks in RIP, including the loopback interfaces. Achieve full connectivity.
  • After using a debug on Router Fred, you notice that RIP is sending updates towards the loopback interfaces. Disable this.
  • The link between Router Wilma and Betty is not allowed to send RIP traffic by using broadcast or multicast.
  • When you start a ping from Router Wilma to 4.4.4.4 you notice the traffic is being sent down the slow serial-link, change the RIP configuration on Router Betty so the Fast Ethernet links will be used. You are not allowed to shutdown the serial link.
  • Create a new loopback10 interface on router Betty, use IP address 44.44.44.44 /24
  • Change the configuration on Router Fred so pings to 44.44.44.44 will be sent only through the serial link, not through the link towards Barney.
  • Change the configuration on Router Wilma and Betty so only triggered updates are sent on the serial link.
  • Configure Router Wilma so RIP V1 updates are sent towards Fred. You are not allowed to change the RIP version on Fred.
  • Configure authentication between Router Barney and Betty:
    key-chain: VAULT
    key-id: 1
    key-string: FREE
  • Create 4 loopback interfaces on router Betty:
    Loopback1: 172.16.0.1 /24
    Loopback2: 172.16.1.1 /24
    Loopback3: 172.16.2.1 /24
    Loopback4: 172.16.3.1 /24
  • Configure a summary on Router Barney so Router Fred will have a 172.16.0.0/22 entry in it's routing table.

    i am wondering if the sequence of required steps all reply on each other
    OR
    is there some steps that need a reset of the configuration to the base Lab Config ?

    this idea came to me after reading this point

    "-Change the configuration on Router Fred so pings to 4.4.4.4 will be sent only through the serial link, not through the link towards Barney."

    which contradicts - in my humble opinion - with its preceding point

    "-When you start a ping from Router Wilma to 4.4.4.4 you notice the traffic is being sent down the slow serial-link, change the RIP configuration on Router Betty so the Fast Ethernet links will be used. You are not allowed to shutdown the serial link."

    So can you - please - tell me if this is due to my ignorance of the possibility to achieve the lab requirement or is it true that both requirements have some sort of contradiction ?

    thank you

    Hi Shareef,

    Excuse me...I made an error in this lab, you are totally right.

    The labs are made so you don't have to revert back to the default config or something.

    I changed the lab so you need to add an extra loopback on router Betty with a different IP address. Then you can influence the router to increase the metric for this prefix.

    Thanks for noticing and the comment!

    Hello

    thank you for your prompt response

    i will try to post my solutions for the lab in the Forum - RIP section

    if you would have enough time to comment on those ; it would be quite grateful

    Regards

    Hi Shareef,

    You posted quite some stuff in the forum :) I'll take a look at your solutions for sure...maybe today, otherwise in the weekend probably. Thanks for sharing!

    Dear Rene

    thanks to you :) don't worry about time , i am not a hurry but i just need to have criticism from a person whom i know is capable of finding the points where i was short to think or to know the best solution

    Where can i get the solutions for all the labs

    Cyril

    there are no formal solutions made by Rene for all the labs [except the MPLS Youtube Video(s)]

    the suggestion was to propose solutions thus give Rene less time to prepare his formal Video solution

    i am currently working on this Advanced RIP lab ; and my proposed solutions are in the Forum - RIP section

    please feel free to criticize or question my solutions

    Hello all

    I am new here and been wondering how to create the loopbacks. Any help willl be really appreciated.

  • avatar
    savage

    According to the lab, does it mean i have to create 4 loopback adapters for router betty on my physical pc?

  • avatar
    ReneMolenaar

    Loopbacks should be created on router Betty...a loopback is just like any interface which can be created by using "interface loopback x" command. Where X = loopback number...

    There is nothing in the configs folder of the RIP Advanced.zip file.

    hi all i am new student in CCNA recently i completed only LAN technology including
    Switch [port sec., VTP, STP, Vlans] and Router [Static Routing, Default Routing ,RIP V2 , EIGRP ]. so Rene what kind of LAB Practice will you suggest me ?

  • avatar
    ReneMolenaar

    Hi Hemant,

    I would suggest to take a look at this article:

    http://gns3vault.com/198-ccna-labs.html

    Those are all the labs you should do for CCNA and in what order. If you feel anything is missing just let me know ok?

    This lab does not come with the current config with the IP addressing on it.

    Hey Rene,

    The configs folder for this lab is empty, could you perhaps fix it?

  • avatar
    baldwinboy3

    I used the image above and configured the IP addressing my self and then did a Cop run start (wr mem) and then exported them to my folder my self. If you do not do save the config first GNS3 will lock up on you. I just used the configuration picture provided and configed up the interfaces.

    i have finished the lab and watched the video, it was great and thank you. I do have one issue the final.cfg files is actualy the initial config files so you need to move the .cfg files from final config to the RIP Advanced config and then upload the final config files please. I want to check my configs to the final config files.

    The below has the following error.

    When you start a ping from Router Wilma to 4.4.4.4 you notice the traffic is being sent down the slow serial-link, change the RIP configuration on Router Betty so the Fast Ethernet links will be used. You are not allowed to shutdown the serial link.

    that should be Router Wilma

    BTW, Great site and great labs! I've done everyone of the RIP labs and got to give you props.

    Thanks

    I'll fix the errors with the configuration files, glad to hear that you guys enjoyed it anyway! 8)

    I just downloaded this lab and there are no preset configs for the routers. The config file is empty and the router just boots into the initial configuration dialog.
