Cisco Borderless Network – ISR Generation 2

Last week I participated in a one-day workshop which took place at the Cisco office in München. The new Cisco vision of the borderless network was introduced and the main focus was on the new Integrated Services Router (ISR) Generation 2.

The whole idea of this vision is that the “borders” in the network will soon disappear and one will be able to connect to the network from anywhere, at any given time, from any device and to any resource. And all this will be done transparently and securely. One will no longer be limited by the device used (be it laptop, desktop, smartphone, etc) nor will he be limited by the type of connection (wired, wireless, mobile, etc). The network will be intelligent enough to adapt and provide a seamless experience.

What interested me the most was the new ISR G2 series, which is a key player in the borderless network concept. There are new versions to all the previous ISR routers and the upgrades are significant. I won’t bother you with too many details, but couple of things stand out:

  • 3 new models of the small 800 series, new 1900, 2900 and 3000 series
  • all of them run a universal IOS image, IOS 15.0 will be released.
  • the image contains all features. The individual features are activated on-demand, as they are needed
  • multi-core processors
  • crypto engines are already onboard
  • field-upgradeable mainboards (Service Performance Engine, SPE)
  • Multi Gigabit Fabric (MGF): the individual modules will be internally directly connected at gigabit speeds

There are of course other changes but I think those are the most important.

After the ISR G2 presentation, a few more things were discussed about topics such as Security, WAAS (Wide area application services) and the ASR 1000 (Aggregation Services Router).

Otherwise things were nice, the presentation was good, no blue screens or anything. And the canteen over there makes really good food! ;-)


Since we had some “very pleasant” experiences with Alice, we decided some time ago that we will switch to another internet service provider, to Deutsche Telekom actually. This friday on the 27.02 the switch is supposed to take place. The thing is, besides the confirmation I have not received anything yet from Telekom: no modem, router, connection info, etc. I wrote them an email some time ago but I got no answer so far.

Today in my lunch break I went to the local T-Punkt in an attempt to find out what’s going on. Unfortunately the lady there was not so helpful. She has to get in touch with the Porting department (since I come from Alice) and she can only give me some news tomorrow, so I have to go there again. She did give me a good news though, apparently if I dont get the connection info in time, I can request some kind of instant login/password so I can use the internet temporarily. Which should be enough because the router I am using now (a Fritz!Box 7270) should work just fine with Telekom.

I hope things will go smooth because it’s gonna suck big time if friday comes and no internet is available. It’s going to be some really dark times for the internet junkies in that house!

Cisco SNRS course

Warning: geeky talk.This is what course “rack” looks like. Each student has his own “pod” (I have no idea why they call it that) which consists of a 2811 router, a 2960 switch and 2 laptops, which simulate a client and a server. The thing is pretty compact as you can see, the trainer only has to plug it into a socket for power then just hand out two network cables to each student.

The course is about securing Cisco devices (routers and switches), VPNs and ACS. I have already worked quite a bit with most of the technologies mentioned in the course so it comes a bit earier for me, I don’t think there will be any problems at the exam. As a “deadline” I have to pass the exam until end of March. I have to pass also the CCNA Security exam until end of March, new prerequisite for the CCSP certification. But I think it’s going to be ok too.

The main reason I came to this course is the lack of books on SNRS. For some weird reason, Cisco hasn’t published any books about the CCSP exams. All you can get is the study guides they hand out in the course, there is not much else. Or at least I could not find anything. If I would’ve found books about this I would’ve stayed home because most of the things in this course can be simulated in GNS3.

Well, back to the class ;-)
