Thanks much Ronnie. What you explain also clarifies the other discrepancies I've noticed while using the Packet Tracer.

Thanks for the reply; very helpful. the ASA is new as it is a 5512-x but thats just being nit picky. I will look at licenses for advanced licenses.

Jonathan,
We'll be covering more in depth troubleshooting during the TSHOOT show and this will include troubleshooting OSPFv3 routing.

Jamie,
No need for apologies. We understand.
We know that a way to pass the exam is to use brain dumps. The exam though doesn't prove you know what to do or how to do it. It proves you know the exam. When an employer assigns you work on the technology and you don't understand it even though you passed the certification, this is the problem. This is when the certification loses value.
There is no better moment than when you earn your CCNA because you know the technology. It's worth the time you put into it!

Damian,
There are a couple of options when preparing for an exam: You can use simulators and/or emulators. Or you can use real equipment.
Ideally, every person would have the equipment they need and not have to worry with limitations of the number of devices. The reality is that with equipment, it also requires you to know more about design than you might know. Hands on is cool but it has it's limitations to build the "Ultimate Lab", you would spend too much money.
Simulators, you have design control and are not limited by number of devices. Your limitations are along the lines of what you can actually do. The reason is that simulators tend to only include the commands and the output related to that LEVEL of training. Providing for limited commands and "canned" output. This means the commands are not running on the IOS but just generating a predetermined output for you to see.
Emulators, are limited to routers. Cisco switch emulation is not currently possible due to the ASICs. Emulators will virtualize the router hardware but you must provide the supported Cisco IOS to run. www.gns3.net But they are resource intensive and require you to know how to get the tool to run before using it.
So...I wouldn't avoid a particular simulator but I would be aware of the limitation of your options. And understand what you're getting!

Paul,
You don't actually have to create a virtual interface to work with vlans. The virtual interface is not created automatically. Usually, you create one on a layer 3 switch, for inter-vlan routing on the layer 3 switch.
In reality, I've never tried to create a virtual interface with a name other than "vlan ###". I just tried this on a 2950, and it won't consider anything other than interface "vlan ###" You can create the virtual interface than assign a description to it though if you're trying to keep it distinguished.

Switch(config)# Switch(config)#interface vlan 222 Switch(config-if)# description East_Campus

So this way it shows up in the show run with the description!

Below is the order the CCENT episodes were filmed in. Most episodes were meant to be independent of the other episodes, but there are a few that build off of one another. Those episodes are usually named "Part 1" and "Part 2".
Intro to Cisco
Initial Device Configuration
Basic Switch Configuration
Switching Technologies
Introduction to Routing
IP Routing Technologies
Intro to Routing Protocols
Intro to OSPF
Switch Technologies
Access Control Lists
Network Address Translation
Troubleshooting

Never thought about renting. I'll look into that. Thank you.

Sorry Laurence, when I typed the response, there was a web link that was in that spot, but it got stripped out for some reason. I'll re-edit the post, but in case it still doesn't work, I was trying to recommend IPExpert (http://ipexpert.com).
Thanks,

Justin,
I ran a quick test on some lab equipment and you are absolutely correct. The adjacency immediately went down after the K values were adjusted. I had never actually configured a mismatch before, I just knew it would cause problems. We probably won't do a show edit for this one since the outcome is the same, but I do appreciate you pointing that out. I love it when I get to learn something new :)
Thanks for watching,

I think that clears it up for me with just one more versifier to see if I really got it.
So as I now see (thanks to you) 2000::/3 is the total aggregate for the Global Unicast Address space.

John,
The err disable state really means that you have to fix the problem that occurred before that port will recover. Then normally you can issue a shutdown, then a no shutdown (essentially resetting the port manually). This brings the port back into the operational mode.
By setting the errdisable recovery cause psecure-violation, you've told it to wait an amount of time before automatically recovering instead of needing a manual recovery. You can also specify an amount of time in seconds to recover automatically. I believe without specifying the number of seconds, it defaults to 300 seconds.

Thanks Don! Of course I meant no offense, but was just curious. :D That being said love the show! As a TwiT listener I love the set!

Charles,
We produce our own content and are not allowed to take the content or format of those resources you've mentioned. To do so would make it their content and not ours. And we've not obtained rights or permission to do so.
Our format follows the official objectives in the order provided by Cisco itself. We follow the exam objectives as given by the vendors to try and give some order. It is to allow you focus in on topics you may be struggling with and be able to cover that within a episode or two but also to provide complete coverage of every exam objective as much as possible. We tried to minimize, tried, as many references to other episodes as "previous" or "you should have already..." (it doesn't mean you won't find it.)
So there is no particular order that you have to watch the episodes!

Thanks Don, that makes a lot of sense. I've been reading through some Cisco docs on internet edge design for enterprise out of curiosity but i was a bit confused in how the ISP's generally work. Really looking forward to the CCNP!

Charles,
We have been working on Cisco vLabs for a while now. We even have several finished. However, we are still navigating the complex world of Cisco licensing and we are unable to release them at this time. Unfortunately, I cannot give you a time frame for when they may be available.
I wish I could be more help on this one, but software/hardware licensing and intellectual property law are a messy business. In the mean time, you might want to consider looking at Proctor Labs. They provide remote access to racks of Cisco equipment for a very reasonable rate. They are what I use for my own studies. For $25 you can get four hours of access to a rack full of routers, switches, firewalls and more which is perfect for IINS.
Hope that helps,

Jamie,
Thanks for writing in. I just dug through my notes and I cannot locate that file. I'm not sure what happened with it. However, I just finished making a similar set of notes for our updated Network+ content, so I think that will help. It is pasted below. Please let me know if you need anything else.

Great job troubleshooting! You're well on your way towards your certification goals!

Can you give an example of prefix?

Laurence,
I saw the question last night but sadly with my Satellite connection, I wasn't able to get to the web pages for scanning. the Episode would be the Troubleshooting Part 2: http://itpro.tv/topic/episode-troubleshooting-part-2/
Laurence, I think you've got a great idea in taking mini-breaks. For study, your mind works best with about 7 pieces of info at one time. Learn about 7 facts, or 7 concepts do a brief break (15 minutes) and then review quickly. If you've remembered all seven concepts. Move on to the next topic!
