I did finish this workbook after receiving access to it yesterday. I will say without giving away any details that I am loving the new format. Not that the current one has issues, but the beta one has great imporvments! Now back to my schedule goals for this week…
Well I have spent that last few hours trying to figure out why R5’s interface e0/0 on Vlan 105 could not ping the routed interface in vlan 105 on SW4. I even got to the point where I did a “write erase” on all the switches and copied the vlan tasks and trunk tasks right out of the solution guide, but still nothing.
If I plugged in R5’s e0/0 interface right into SW2 where the routed port on SW4 was connected to I could ping without an issue. So I decided well there has to be a spanning-tree issue going from SW1 where R5’s interface is plugged into. So I start checking spanning-tree and saw the root port for vlan 105 is going over to SW4. Now I know further ahead in the switching tasks I will stop all vlans except 102 from going over that trunk link, but the solution guide is showing they can ping before that trunk link is configured for vlan 102 only. So I just shut that trunk port down on SW1 and sure enough all my pings start going through. Could it have been just a forwarding loop?
That is what I get for being proactive and checking my end to end connectivity right after I configure the trunks links I guess…
- Internetwork Expert class on demand day 1 complete
- Internetwork Expert class on demand day 2 started ip routing part I last night
- Started internetwork expert workbook II lab I (hopefully can move through it over this weekend along with some more hours of the cod.)
Goals for this week were
- Start the class on demand and move through as much as I can
- Drop five pounds 😉
- Start workbook II again
- Schedule my lab exam
Goals for the upcoming week
- Move through day 2 of the cod and possibly day 3
- Finish lab 1 and start lab 2 (although thinking about hitting the redistribution section in this lab is making me nauseous)
- Drop another 5 pounds using the BMR!
Well I have for sure hit my struggle. Hopefully that is over. I started back up the eighty hours of COD so I am hoping to push through those again. I am not going to rush through though this time as I did before. I need to SLOW down and absorb as much as I can. Not sure why I was in a rush to begin with. Plus I will kind of have to keep the pace slow with real life dictating the way it does. Hopefully though I can use every spare moment I have here at home to watch and study the classes.Â
One thing I think I need to do is come up with multiple goals and stages to help benchmark myself. Try to get to “X” by this date and so forth. I think that will help me from getting scattered all over the place again. All you have to do is readÂ Ethan’s blog to see whatÂ work and determination will get you. Need to make sure you just keep the drive alive inside you.
I am hoping to mix up the class on demand material with the workbook II labs as well. Since this is my second time going them I am sure I can handle doing some labs as well ;).
Since I really don’t have the time to get to a five day boot camp I decided to go ahead and add the Internetwork ExpertÂ five day class on demand bootcamp to my end to end program. Any vacation time I have until September I am saving for son’s birth (I am nervous all the ultrasounds are wrong and he is a she!) So I can’t even think of doing a bootcampÂ until October and Internetwork Expert is done with the five day camps after August in the U.S. Hopefully I will be able to attempt and pass the lab by the end of the year and not have to worry about it :D.
Does anyone remember the MCSE crazy back in the late 90â€™s? In Western NY we had a company called Ikon that promoted â€œTech 2000.â€ The cost was $10k and they offered you the promised land after they taught you and helped you pass all your MCSE exams in either NT 4.0 or 2000. Now I remember the MCSE being the big thing back then until these training companies where helping push out MCSEâ€™s non stop for a few years. Now in the end the training company was really the only people that made any money off of this. Most of the people I know that did this ended up either bankrupt or back in college ;).
Now my concern is that our present day CCIE training companies are starting to do the same thing. Companies are offering 12 day lab bootcamps now for 10k. Everyone else is pushing new end-to-end programs for some big bucks. Is anyone else concerned about the CCIE label? Am I just paranoid from the MSCE craze? With the CCIE being a tough lab exam make sure it never suffers the same fate?
“If you build it, they will come. So hold onto your hats now that the world Cisco router rootkit, reports a story from IDG News Service. Sebastian Muniz, a researcher with Core Security Technologies, developed the rootkit for Cisco’s Internetwork Operating System and will show it off on May 22 at the EuSecWest conference in London. Rootkits are stealth programs, extremely hard to detect. For the most part, they are aimed at Windows. They are typically used to capture desktops and servers for botnets, or to embed keylogging code or spyware. (Although, as the story points out, Sony BMG Music was perhaps the most notorious rootkit. The company built it for DRM, to stop unauthorized CD copying). Rootkits are a favorite of the financially motivated criminal hacker, experts say. But now a rootkit can be placed on a router. What kinds of use can such a thing accomplish? Will it be an easier way to gather multitudes of passwords stored in configuration files? No doubt now that rootkits have been proven for IOS, the world will soon find out. Hackers are nothing if not creative.”
I can always find a good read from Ivan!
“If youâ€™re serious about the high-availability of your network, your remote sites have a primary and a backup link into the core network. In the old days, the backup link was usage-charged (think about ISDN and X.25), and the important issue was to reduce the usage of the backup link. These days, we usually use fixed-cost primary and backup links (for example, Metro Ethernet for primary link and Frame Relay or ADSL for the backup), and once the top managers realize that, they want us to utilize both links all the time.
It doesnâ€™t take much to convince anyone (even people who have never been involved in networking) that it doesnâ€™t make sense to load-share between a 20 Mbps symmetrical fiber-optic link and a 1Mbps/256 kbps asymmetrical ADSL link. The next idea the managers get is usually very predictable: why donâ€™t you transport certain applications over the backup link? Welcome to the murky world of policy routing.”
Cisco Subnet over on Network World has an article from Vyatta stating better performance from their product than Ciso’s 2821’s and so forth. Here is my problem with their gear: It runs from a PC! Now I am a big open source kind of person, but I will never run any routers off of PC hardware. PC’s are too prone to failure. So you start to look at 1u servers with all redundant hardware. Which starts to become even more costly. I have had plenty of servers as well that lost motherboards, raid batteries and so forth. Plus if it does crap out on you, are you left reloading the whole OS again? Any guess as to one of the reason I love working with network hardware? My backup and restore consists of “copy start tftp, copy tftp start…”
The last thing I would ever want to worry about is PC/Server hardware on my node ends…
