JunOSphere

One of the main concerns with Juniper certification and training was how to find access to equipment.When Juniper introduced JunOSphere the cost for 1 month was around 1600USD and I believe you had to pay the whole amount at once and use the routers within the same month (?),however, now you can purchase a small day sessions for just 50$/day and using it whenever you want.  Check the Juniper website for more information. I will try to buy a session and provide more feedback about that.


So far, good job Juniper.

JNCx Lab Topology

I have been trying to find out something like that in Internet and after couple of days looking I decided to make it myself. The configurations I am going the share are based on the topology below:

All this is Olive11.1R1.14 with recommended configuration of quad core CPU and at 8G ram and fast hard drive/SSD?  I am running that on FreeBSD 8.2/64x. All images are in separate folders called r1; r2; r3 etc. I believe the configuration example below should be enough for everyone who wants to run Olive to extend my config with more routers.

Installation is straightforward

cd /usr/ports/emulators/qemu ; make; make install

juniper - part 1

Since I started a new job I really don't have much time for studying for the CCIE lab - Looks like I will delay it with another year and during that year I will try to improve my Juniper knowledge by taking couple of exams in the Service Provider area.  So I assume most of my new posts will be juniper networks related.
