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?
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.
So it does say that BB routers are not in candidate control and used for injecting routing information in the LAB. So i guess i will save some money by using the Probe to inject routing information...does it sound fine? I am using these probes and their services to inject traffic of all kind for doing lab and it feel like a production environment. So i guess have to write a script to inject routing information . BTW any body want to use it or try for free??? I can manage some thing as it is already on Cloud so you can access the service. It is some what like IxChariot, but based on cloud .
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.
I know that BB1 is used as Frame relay switch, have already bought one . The other 2 are for injecting routing information and can be anything not only BGP (Not too difficult to imitate if you are a programmer too ).
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.
@Travis.Yes i know the routers are there for a reason but just asking because i am curious .
@Scott. Now i get it, but can i know how to generate different type of traffic in the Lab while configuration and checking while doing show commands or showing counters that everything is going good. For example if i want to do a lab isn't it good to have different kind of traffic in Lab...Is it done by BB routers? I have personally find QoS quite difficult to tune without traffic generators in the Lab.
@Martin. I know but i already have half of my CCIE lab and few HP, Juniper equipment . I personally think it is way better to study and play around with real equipment. Going to be build small version of Uber Geek lab (Can't beat 2 million $ ).
