Laurence,
I believe the RSTP was covered here:
http://itpro.tv/topic/episode-switching-technologies-part-1/
I'm looking at the notes where it looks like we covered it. I'm not sure how in depth compared to the question you saw the exam.
With the multiple spanning tree, that one I believe we mentioned but didn't do any configuration on it because we normally would see that covered in the CCNP SWITCH level exam. I'm surprised by the configuration question on MST.
Thanks for letting us know!
Cordially,

Laurence,
On this one, if I said it would fail back, I would be incorrect on this one. Beginning with Cisco IOS 12.2 and later, both cannot be active. You can configure both but both cannot be active simultaneously. If you set both, the enable secret will take precedence over the enable password.
I will try to add some Errata on that episode. Thanks for pointing that out...hate to have missed this one do my mouth moving before my brain!

Hey Don,
Here's the three I've noticed (though I think the middle one was the only show with true notes):

Thank you!

David,
It could be a number of things, but my best guess would be a bad NAT configuration on the DD-WRT router. Most likely, the DD-WRT box is configured to NAT hosts with a source IP of 192.168.1.0/24. You Linux box is in the 192.168.3.0/24 subnet so it doesn't match the NAT rule. The DNS lookups are most likely working because DD-WRT uses DNS Masq by default so the lookups actually happen against that box. I could be completely wrong, but that is my first thought.
If that is correct, then there are two possible solutions:

Update the NAT rule on the DD-WRT box to include 192.168.1.0/24 and 192.168.3.0/24. Configure NAT on the Cisco router to hide the 192.168.3.0/24 network from the DD-WRT box.
Option #2 would result in double-NAT which is not the greatest thing in the world, so I would go with #1 if I were you.
If that isn't the case, we can do some more digging, but that scenario definitely fits the problem you are describing.
Thanks for watching,

Is there another good practice exams I could purchase that you would recommend? It is hard to know what is trustworthy out there and market is so full of stuff that is not worth the paper it was printed on.

Mr. Allen, I owe you a *few* beers if this actually works. I struggled with this and Allen Bradley's RSLogix/RSLinx for YEARS.
Does the hex value = the COM port # to lock it to? or just lock it as it sits?

Dale,
For the first question, you're scenario sets this up very nicely for the use of multiple subnets. If the company has grown over time, it's like to grow again and likely to need multiple departments too. Creating multiple subnets will help segregate traffic according to your business need (e.g. HR Dept traffic separate from the Marketing Dept). Also for future scalability, if the business continues to grow with one network (such as a 192.168.1.0/24) you'll still need another network. Let's say you pick a 172.16.1.0/24 next. This will work but you'll not be able to take advantage of things like route summarization. Creating a solid logical network scheme will allow for scalability, segmentation and routing efficiency.
For the second question, if it's a point to point connection you could use a fiber optic for the connection:
you're looking at ethernet 1000 Base LX (max of 1804 ft).

Thanks Ronnie!
Ill look into the link you posted and reply to this thread if I have any follow-up questions.
Thanks Again!

John,
I think I see what you are asking, as I am looking into learning/earning the same certifications.
Based on ITProTv's Course Library identifying the Exam number for the CCNA Routing & Switching as 200-101 and comparing it to Cisco's website ( http://www.cisco.com/web/learning/exams/list/icnd2b.html ), then I believe yes, the CCNA Routing & Switching Course is the ICND2 you are looking for.
Cisco offers two ways to earn the CCNA Routing & Switching Certification. For the uninitiated newbies, like me, they offer the two part CCENT (ICND1) and the CCNA (INCD2) exams. Or for the initiated IT people; those looking to re-certify, they take the Exam 200-120 CCNA (which combines both the ICND1 & ICND2 exams into one long test). Both routes lead to the same results.
I hope that helps, as this sounded like the same question I had going through my mind last week while I was researching certifications and ways to educate myself to earn them.

M-S-G,
Our Buddy!! You're correct. Check the configuration register is the key. The default system startup register is 0X2102. The last 2 is the significant portion 2=0010 in the startup. This tells the system to startup the device normally. check the IOS and then load the config from NVRAM. but the 3rd number 0000 indicates that everything is A OK. If you change the configuration to a 0x2142, you're telling it to start as normal but the 4 indicates that you're not to load the startup up config. This is typically called password recovery mode. If you reboot, even after saving the changes, it will not load them back into RAM from the NVRAM if the register is this way.
So check your configuration-register settings:
use the show version command:
Router#show version
*at the end of the show version output, you'll see the configuration-register that the system has set.*
Then to change the configuration-register:
Router(config)#config-register 0x2102 (to change back to normal startup)
Router(config)# do Wr
Router(config)# reload

Charles,
Thank you for the heads up on this. It looks like there was a typo in the filename. Our web guys straightened it out and the video is playing for me now.
Thanks again,

Yes, Don has answered this question here.

Jonathon,
Great questions. Here's my go at answers.

The labs under the new objectives haven't really changed much. The primary changes are that RIP is completely gone, and IPv6 is added in. Also, the IOS on the exam is now 15.1 instead of 12.4. If you are running a newer PacketTracer it should have 15.1 already. For the most part, your old PacketTracer labs should still be fine. If you are looking for alternative labs you should check out the PacketTracer Network. They post labs made by the community and they are really good. Another great source of study material is the PacketLife website. The site author has put together some of the best study sheets available and they are completely free. In just a few days we will be announcing our partnership with MeasureUP to offer all of our subscribers access to MeasureUP practice exams at no extra charge. Look for that announcement by the end of the week. A while ago I made a list of all the commands necessary for the CCENT exam.

Yep, we re-shot the EIGRP episode to provide a more easy to understand introduction to EIGRP. Then, we had Jason, our video editing wizard, chop up the old episode and turn it in to an EIGRP troubleshooting episode. All in all, it turned out nice.
Thanks for the feedback guys,

Nevermind, I figured it out.
1.) My post didn't display correctly.
2.) I didn't post any configuration.
3.) Im an idiot.
4.) The answer was that I had setup the incorrect sub interfaces on the routers.
Thanks,

M----------

Dan,
That is true, the machine will retain its IP for the duration of the lease when the VLAN is changed. The trick I use to get around this is I shut the port down when I change the VLAN and then turn it back on again. For example:
Switch(config)# interface fa0/24 Switch(config-if)# shutdown Switch(config-if)# switchport access vlan 400 Switch(config-if)# no shutdown Switch(config-if)# end
The PC will see the network card reset and perform a new DHCP discovery. That saves you from having to go to the individual PCs.
Hope that helps,

Paul,
There are a number of good free and pay Cisco emulators that are out there. They are an amazing resource for people who are trying to learn to work with Cisco equipment, but don't want to spend a ton of money setting up a full lab. Here's a few options for you:
GNS3 - GNS 3 is my personal favorite. It only emulates routers, so it won't help with switch labs. However, what it does is pretty impressive. It emulates the Cisco router hardware, so you can run standard Cisco IOS images on it. That means you get 100% of the functionality of a real Cisco router without the hardware expense. Its performance is not spectacular, which is what prevents people from using it in production and keeps Cisco happy, but it is great for a lab. You can learn more about it here: http://www.gns3.net/.
Boson Netsim - Boson Netsim has been around a long time. It is not an emulator, but a simulator. In other words, you are not running the Cisco IOS, but it is merely taking commands that you type and displaying results based on what would happen on real equipment. That means it does not give you 100% functionality like GNS3 does, but it does give you all of the commands that show up on the exam. It also supports switches which gives it a leg up on some of the other products. You can learn more about it here: http://www.boson.com/netsim-cisco-network-simulator
Cisco PacketTracer - The Cisco PacketTracer is another emulator like the Boson Netsim. However, it is much more polished and is a superior product in my opinion. It allows you to build a custom network and work to your heart's content. There are even entire online communities built around sharing PacketTracer lab files. The only issue with the Cisco PacketTracer is that you cannot buy it. It is provided free of charge to students enrolled in the Cisco Network Academy and not sold through any retail outlet that I am aware of. That being said, copies of the software can be found with just a few minutes of Google Kung-Fu. You can learn more about the PacketTracer here: https://www.netacad.com/web/about-us/cisco-packet-tracer
eBay - The final entry in my list is eBay. Sometimes emulation/simulation isn't good enough. Currently the exam features Cisco 2901 routers and Catalyst 3560 switches. If your pocket book is big enough you can pick up a handful of each and get to studying. If you are on a budget, though, there are alternatives. For example, my all-time favorite router is the Cisco 3640. It is a beast of a router that can support darn near every feature Cisco has to offer. You can find them all over eBay for under $100. They won't run the 15.x IOS track, but the 12.4 track contains all of the commands on the exam. Just make sure the router comes with the interfaces you need and enough memory to support the advanced feature sets. I recommend a 3640 with at least two Ethernet interfaces, 128MB of DRAM and 32MB of Flash. Keep in mind that you can buy one with less dram/flash and upgrade it pretty easily. On the switching side, the exam uses the Catalyst 3560, but a 3550 will support almost all of the features you need as long as you load an EMI image on it as opposed to the SMI image most of them come with. The hardware is the same, but the software image determines whether they support layer 3 routing or not. Like the 3640, these can be found all over eBay for under $100 each.
Hope that helps,
