Routers and Voice Lab – Part 2

Yes Definitively , it will be difficult to have dedicated hardware so after more investigations , GNS3 is amazing and can do a bigger part of the job but need again to emulate this on the server so it is taking more resources. Take in mind that you can’t play with DSP so PRI connections and so on.

Think about 5 servers and a router Topology with at least 4 routers ( HQ, Branch 1, Branch 2, PSTN/CME). So it is becoming huge to maintain for hardware resources !!!

Routers and Voice Lab

Ok It is now time to start slowly on the lab again .

As It seems also clear that I will not have specific dedicated hardware , I will also try to push the discovery of GNS3 as we can already simulate a lot with this tool.

So tonight , I will investigate more in GNS3….

Motivation is still here and I will pass my exam before the end of year . Probably end of October or beginning of November .

Great News

Hi,

This morning, I passed successfully my CCIE Voice written exam … I’m feeling well now and will take some rest before to go ahead very soon with the lab portion.

What a good news …. 🙂

Last day before the target

Urgh 🙂 it is the last day before the exam …. Tomorrow at this time , I will be sitting in the exam room.

As usual I’m feeling that I’m missing some points but I’m on the starting blocks to do my final study day.

The best I can do is to continue for tomorrow and all this study is not lost as It will serve for another day if I need but is also very helpful for the OEQ .
