Best. diagram. ever.

Assuming they are adjacent wouldnt just using CEF and per packet distribution on both end accomplish this as well?

You can also modify the T0 through T5 EIGRP parameters to get rid of the delay multiplier – saves a lot of aggravation when trying to match the metrics.

P.

Please confirm if it is a typo??

In the topology table, C will have two possibilities to get to network D:
Via D, with an AD of 1
Via C, with an AD of 4+1 = 5
**** Should this be “Via E, “

Has anyone 802.1q tunneling working successfully in IOS?

I have been trying and continually get the error:
Command rejected: Gi1/48 doesn’t support 802.1q tunneling.

I have had my fair share of poor technical support from TAC, but I usually have little problem getting the case re-queued with a competent tech. When I do get one, they are usually super-knowledgable and like you say, have no hesitation to logging into your equipment remotely. I also like the fact that you’re given a direct line to the support person you’ve been dealing with. This helps keep things simple when you’re dealing with a complex issue as you don’t need to re-explain certain things to the next engineer you get on the phone.

I have had horrible experience with SonicWall’s support team. No matter what the issue, they always tell you to upgrade to the latest firmware before they even hear your problem.

Nice review. Finally some sanity. Anyways, bein g that this post is about 8 months old, how is the service so far with go daddy?

can we use with in single peer-group to put multiple out route map..if yes then what is the configuration

I would say you definitely are a Cisco customer evangelist : )

Thanks for sharing the story.

Hi,

I just came across your website somehow on Google and was reading some of your entries; I noticed you seem to be very knowledgable on a variety of topics. I’m leaving this comment because I would like to pose a question. I passed my CCNA in 2003, and it just expired in Jan, 06. I haven’t renewed it yet, but I am scheduled to take the test very soon. I have a fair amount of experience, since I have been working as a network administrator. I’m also scheduled to start a 10 day CCNP bootcamp at the beginning of May. Any suggestions for the CCNA and the CCNP? I’ve heard that the CCNA has gotten exponentially more difficult these days…

A reply via email would be good if you have time, if not, I understand.

Thanks for the help,
Chris

Dude

You are better then me, but i played a trick . I did my CCNA in 2000 and i was such a lame that i completed my CCNP in 4 years . I gave 1 exam each year. Once you are in a job you hardly think of certifications but i think its a high time for me to go for CCIE.

Great thought!

Count me in.

I started publishing a blog as I started preparing for my CCNP and CCIE. (I recently got my CCNP after I started the blog.) The blog is at http://ciscostudy.blogspot.com and one recent article that I would like you to link to is

http://ciscostudy.blogspot.com/2006/03/understanding-ospf-default-route.html

The main format of my blog is that I try and frame questions around concepts that I think are important in the topic I happen to be studying and let the readers come up with the solutions. If people post comments, I engage in the dsicussion to learn more and provide my solution if necessary.

Once you have a number of Cisco blog links in this thread, I will put up a post with the links on my blog.

I have to respect your point of view – there are too many paper gurus in this field. But, I have to disagree with your recommendations to your students. I have been in the networking field for about 8 years now. I began out of the blue – decided I wanted a career change. Picked up a book and started reading – and started taking cert exams. I also ambitiously found an avenue into the field and ended up getting a cisco class and MCSE track out of the deal. But my real education has been self taught by reading manuals, or cisco press books, or … blogs even. I’m constantly searching online for answers to questions – referencing RFCs etc. etc. Regardless, if certifications are the impetus and measuring stick one needs to dig into the material and learn it – so be it. But one should not necessarily expect to get a job with large responsibiltiy and pay check based on just certifications – unless of course they hold a CCIE – that helps. And that, is what I am currently pursuing – as soon as I recert my CCNP next month. Point is – to do well in this field the important thing is to dig in and start learning – it is a constant process – the field changes to quickly. Get hands on through simulators, or, if you can afford it, buying used equipment. Start with your CCNA if you want – but that is just the tip of the ice berg. Move right into your CCNP – read read read and practice practice practice – you will learn it.

Your explanation of feasible distance and advertised distance with regard to choosing feasible successors is incorrect.

If the advertised distance of a non-successor route is less than the feasible distance of the successor, then it can be a feasible successor.

Thanks for the correction, I got it backward in this article.

May be an idea of saving operational cost using 1Mbps back up site to site VPN in regards to frame relay,leased lines and ATM’s.

Idea of operational costs using different smartnet contracts

I like to have a general translation of kilobits to kilobytes and vice versa

Luckily I finished mine back in May! Yay! I’m pondering a CCIE, but the return on an IE in this area is very little; hell no one really wants to pay an NP around here…

Chris

Great review!
I decided to check this video out before I sat for my ccna and I must say it did help. Probably not to be used as a sole source of study, but definatley a help. As you said, I’d like to see more releases for more advanced topics in the future.
Cheers

I am a bit confused, about Via C, with an AD of 4+1 = 5

I understand the 4 bit which is the AD between the next-hop to the destination.

Why +1 instead of +2 which is the cost of between local router C and the next-hop router which is E?

maybe I got it wrong because I thought

FD= AD of next-hop router + cost between local router and the next-hop router

I’m using a godaddy virtual private server but don’t seem to have access to iptable. Did you do anything special?

How much RAM does dynamips use on your box when you’re simulating all of these routers? I’ve been thinking of selling my CCIE rack to off some of my CCIE debt…

Thanks,
Chris

This works on a 2960 too.

Performance:
We can configure each module independently and add up the hierarchical approach with the core access and distribution layers approach within each module. This gives independency of functions such as pushing the security outwards at the access layer then implementing intelligence at the distribution ex: QOS load balancing…
We now have explicit boundaries to actually define the interaction between modules and applications, note that we now have a building distribution and an edge distribution.

general note
From a global point of view it looks like core distribution and access yet in details in is small blocks of core distribution and access.

Just wanted to introduce myself, been a lurker on here for a while. Are there any subjects that we can’t talk about on here?

your blog is awesome.

Hi,

Have a look at http://www.cisco.com/en/US/tech/tk365/technologies_white_paper09186a0080094cb7.shtml

Minimum MTU along the path is an EIGRP metric, with the default K values it’s not calculated though. It’s there, look at the show ip eigrp top output.
