BB routers in lab

Hello

       The BB routers which are used in lab to generate the traffic i guess, is it compulsory??? I mean i am building my own Lab and is it necessary to buy them? I work in a company which has a network monitoring tool based on Cloud computing, i use it for my consultancy work for intelligent troubleshooting and testing after configuration, i can easily use their hardware probe to generate any kind of traffic in my Lab environment. Can i replace the 3*BB router with there probe? Or does these routers serve some other puropose?

 

Regards,

    The backbone routers are there for routing adjacency and route injection purposes really. This forces you to learn how to troubleshoot adjacencies and route advertisement/acceptance issues from one side only. 

     

    So yes, if you want to have the full lab experience, you will need the BB routers.

    follow this INE topolgy http://www.ine.com/topology.htm

    if you are CCIE  building rack;

    you may consider GNS3 for routing part.

    well, not so fast;  if u look closely, one of routers have 2 functions:

    BB1 / Frame Relay Switch 2522 12.2(15)T17

     

    if u ask Brian MaGahan nicely, maybe he can give u configurations for backbone routers to see what else is there; I guess BGP for sure.

    Unless your probe can establish BGP/OSPF/EIGRP adjacencies, and can do IPv6 - then no, you can not use your probe.  They have routers in the topology for a reason.

    They are there to generate some traffic, and to have some peering that you don't really have control over the configuration of!

     

    You can use whatever you want as long as there is some variety in configurations there.  I'd hesitate connecting to a live network as you don't accidently want something going bad in your lab and bleeding over into your live network! 

     

    As for the traffic probe or traffic generator, it's not so much "traffic" that you want to generate as it is routing stuff and basic peering, so I don't think I'd worry about the probe they have.

    Many people have use GNS3 with 4 real switches!

    Buy 2 c3560s and 2 c3550;

    You also need correct (or close to) IOS version and distribution;

     

    either way, good luck
