- patricks, on 10/12/2007, -0/+7While this article is about as elementary as it gets, it still doesn't hurt to see such things on digg. The amount if 'internet professionals' that haven't the slightest clue how networks are created is very frightening.
take my boss for example... - sirket, on 10/12/2007, -0/+7Seriously- If you don't already know this by heart- you probably shouldn't be anywhere near a router. I find myself terrified of late by just how little the networking people I run into actually know. Sure they can set up OSPF (so could my cat) but try asking them anything specific and they have no clue. "So, how would you go about filtering LSA's within an area?" "How would you go about filtering LSA's on an ABR?" If you get a correct answer for something even this simple it's amazing.
And don't get me started on damned Windows admins who insist on listing their job title as "Network Administrator." Just because you admin a collection of Windows computers on a network, does not make you a network administrator. It makes you a system administrator. And don't say system administrator either- that's reserved for the Unix folks. Say "Windows Server Administrator." That's at least accurate. If you don't deal with OSPF, EIGRP or BGP on a daily basis you are probably _not_ a Network Administrator. - gadgetuk, on 10/12/2007, -0/+6@BGPWhore
If you really knew that many CCIE's you'd have yourself a cheap Ultra 10 and a copy of IoU for all your cisco practice needs. You obviously have zero clue.
There is the "Drake" written exam followed by a full day lab session with a CCIE proctor. Then there are many different specialisations and the lab varies not only by time but by where you take it and the proctor on the day. It is extremely difficult and - last I heard - had an 80% failure rate for first time attempts. I'm not saying that every CCIE is an ace or that they've all achieved it without some unfair assistance but I'm fairly confident that they all know more than you. - dbr_onix, on 10/12/2007, -1/+4What is the purpose of this? It seems most people who need to know this (how to use IOS) already should know this, any for people wanting to learn to play with Ciscos, there is far better guides than this (it's a far too specific subject)
- Ben - xlocust, on 10/12/2007, -0/+3doesnt the CCIE cost like $1500 and have a passing rate of 15% or something crazy low like that?
- radioactivesmrf, on 10/12/2007, -2/+4Not bad just seems like it's obvious to me but it might not be to everyone i suppose.
- naiku, on 10/12/2007, -0/+2Techrepublic has a lot of good articles.
Very basic. If they only had a couple articles about QoS so i can pass that CCVP exam x.x; - s1rk3ls, on 10/12/2007, -0/+2I was waiting on you to finish that statement...
"...no really, take him... please!"
*badabing* - gadgetuk, on 10/12/2007, -0/+1IOS was created from a Unix base (BSD I think)... so there.
- osbjmg, on 10/12/2007, -0/+1Yea, not sure why this article took 2 pages... I wonder how much money you can make by creating fluff articles such as this by splitting it up into 2 - 3 - 4 pages?
- BGPwhore, on 10/12/2007, -0/+1@gadgetuk
my my, those are nice conclusions that you draw from such little personal info I post.
>have yourself a cheap Ultra 10 and a copy of IoU
why bother emulating when I have access to the full range (except CRS)? using the hardware will always be better. and last time I checked getting 2 basic routers is way easier and cheaper than sourcing an U10 and a copy of IOU (which BTW is illegal unless you are a Cisco employee). I've always preferred a lab over an emulator, be it IOU or Boson or whatever.
>There is the "Drake" written exam - last I heard - had an 80% failure rate for first time attempts.
well I'm still saying that the "Drake" exam is only changed every 6 months (but you can take next year's "drake" as a beta for 300$) and the lab is always the same on a 6 month period. fail first time, look up the answers and retake it.
unlike you I won't resort to drawing conclusions on your knowledge but in my 10 years in the tier1 ISP engineering and ops industry I have seen a steep decline in the quality of people claiming CCIEs. Granted Cisco has improved its policies in the past 2-3 years regarding test turnover and cheating but it is still not it. I'd still go for a Juniper Cert today if I needed one. CCIE used to be a guarantee, I don't regard it as such anymore.
lets not get into a FanBoy argument shall we? - inactive, on 10/12/2007, -3/+4Yeah I CCNA,CCNP certified so I'm tough guy :D
I think they almost write the whole stuff from scratch, but it doesn't matter because the whole IOS n00b toy comparing to any BSD or Linux, you play with couple of hours with it and you pass on the exams :>
"Keep in mind that filtering by MAC addresses is not a security measure—someone can easily change the MAC address in your operating system."
This why we don't use macfiltering since 10 years...
Well I really don't want to flame with this article is ***** so I advice for everyone to download Backtrack > http://www.remote-exploit.org/index.php/BackTrack
and use Cisco Global Exploiter + Cisco torch to 0wn as many device as it possible :>
Have fun :D - inactive, on 10/12/2007, -1/+2Nothing is impossible for the man who doesn't have to do it himself.
BTW the default user,pass cisco/cisco usually :p - nsummy, on 10/12/2007, -2/+3A pretty pointless article considering the first page is dedicated to teaching what a mac address is. If you don't even know that you have no business on a cisco router to begin with!
- baalpeteor, on 05/06/2009, -0/+0well maybe they only need it in the short run :-O.
- rusty_g, on 10/12/2007, -1/+1it's nice to read about something like this, especially since I am working on my bachelor's in Informatino System Security... i am actually learning a lot of this stuff in my class right now anyway...
- simontemplr, on 04/17/2009, -0/+0routers? Do you mean Switches Layer 2? Yes you will see MAC Addys in ARP tables.
I just do not understand why a person tries to spoof their MAC Address? It does not work in the long run, neither does it work when spoofing IP addresses. - gadgetuk, on 10/12/2007, -3/+2@moonwell
Ok, simple example, how exactly would you create a OSPF>BGP distribute list to eliminate RFC1918 distribution using BSD? It's about 5 lines in IOS.
Bit more complicated, can you VRF for MPLS on BSD? How about TE in the core for multiple CsC VPNs?
I love BSD - it's an incredibly powerful tool - but it's the wrong tool for the job that Cisco IOS does very well. - BGPwhore, on 10/12/2007, -2/+0Man save up you $$$ and get a real certification from Juniper.
crazy the amount of CCIEs I meet these days that don't know squat...
(that's what you get when there's only one question sheet every 6 months and1 guy in the team goes to get it's CCIE, memorizes the questions and hands them to its colleagues so they get a free ride on their test)
I hear Juniper's at least has a dissertation on specific subjects and they won't certify you unless you've proven there and then that you know your stuff.
BTW want QOS: get 2-4 cisco8XX routers on Ebay (don't pay more that 50-70$ each) and build you own lab, these are DSL CPEs so they have at least basic QOS built into the IOS and have fun!
pissed_at_Certs should be my nick. - spider418, on 10/12/2007, -7/+4Enough with apple already!
What about Ethernet *PC* addresses !? lol - wickmeup, on 10/12/2007, -39/+1IOS is neither Unix or Linux; this belongs under another topic.
