CCIE home rack – Ubuntu persistent net rules

By On November 26, 2011 · Leave a Comment

In one of my last posts, I was writing about my CCIE home rack which has one server that runs Ubuntu + Ethernet Quad cards + Cisco switches. Before connecting the cables between server and Cisco switches, I had one problem that was driving me crazy.

I have three Ethernet Quad cards connected in 3 PCI slots in my server. The issue is that sometimes (quite often) the port numbers were changing during the reboot of my client. To [...]

Home lab for CCIE exam training

By On November 17, 2011 · 5 Comments

Before I started with my preparation I was in front of a dilemma. I knew that I will need a rack to practice for CCIE training and I had two options: remote rack rental or home rack.

I put together side by side all pluses and minuses about the two options, but somehow I couldn’t decide which solution to choose. Both options have good and bad parts. You’ll have to figure it out which solution you can afford and works best in your case. My [...]

New blog section – Certification

By On November 17, 2011 · Leave a Comment

I don’t know how many of my blog visitors had the curiosity to visit the About section to read something about me. If some of you did read that section, then you already know that I have several certifications from Cisco and other vendors and I’m on my way to CCIE. A long road with a slow progress due to my busy professional life.

These being said, I want to announce a new section of my blog called “Certification”. In this section I [...]

RIPv2 MD5 authentication – routing trick

By On September 30, 2011 · 5 Comments

I must admit that the following example is more a CCIE exam topic and not a solution that you would add in real network environments.

Let’s assume that we have the following topology:

The Loopback interfaces are there to have some networks which we will advertise into RIPv2. The request for this topic is to have RIPv2 MD5 authentication in place, Router1 to receive all routes from Router2, but Router2 will not have any prefixes in routing table from [...]

InterVLAN routing using Private VLANs

By On September 23, 2011 · 3 Comments

Private VLANs  is one possible solutions for service providers to offer secure connections to their customers and avoid inter-vlan communication in the same switched environment.

I’m sure that you heard (and most probably practice already) InterVLAN routing. When it comes to Private VLANs the routing part may be a bit tricky. Keep in mind that this is not something that I would recommend to use as a standard in a productive environment, but for things like Cisco exams (e.g. CCIE R&S) or last resort solution, [...]

Draw network diagrams online (with Cisco stencils)

By On September 17, 2011 · 1 Comment

I’m a Mac and Linux user and if you are like me, then you have the same problems drawing network diagrams. Microsoft Visio does not have a version for this platforms. I’m not saying that there are no alternatives to Visio on Mac or Linux platform, but most of them are either limited in features, expensive or need some tricks to use it (as I described in one of my early post).

Finally I’ve found [...]

Cisco Easy VPN Router-to-Router

By On September 16, 2011 · 1 Comment

Cisco Easy VPN is not a new technology. Actually it is pretty old, but still used by many companies or people to connect remote site / remote workers to headquarter.

A few days ago I was looking to connect a remote site in a simple way but still secure and a colleagues suggested me to use Easy VPN. It supposed to be a simple configuration and it was after solving all issues that came into play.

First of all, I needed an Easy VPN Router(client) [...]

Would you do such things to an ISR 819?

By On September 9, 2011 · Leave a Comment

Lucky there is a big disclaimer at the beginning of this video. Otherwise I would be tempted to test such things and then plug it in to see if it still start (at least) and run.

It’s a nice commercial from Cisco, but to be honest I feel bad for this poor device:
