Finished Narbik’s Advanced Technologies Vol 2

First off, I have been moving VERY SLOWLY through these workbooks. I should have finished Vol 4 today  but I just finished Vol 2. The problem with these workbooks is the fact that you have to reboot after every lab. Now this is a good thing but it def wastes time and then you get distracted. I know...

Narbik’s Soup-to-Nuts Workbook BGP Labs

I spent all day today and yesterday working through the BGP labs in the workbook. As it was the case with other technologies, BGP labs started off at a basic level and ended with very advanced level labs. Some of the tasks were repeated from lab to lab and that really helped grasping the concept. I believe...

Narbik’s Soup-to-Nuts Workbook OSPF Lab 7

"Lab 7 - Filtering routes in OSPF" One thing I have definitely learnt while working on these OSPF labs is that by default OSPF advertises loopbacks as /32 and in order for us to advertise the correct mask, we have to use ospf network type point-to-point. router(config)#interface loopback0 router(config-if)#ip...
