Did a final mock before lab and barely failed. I got 71/100. To my defence I did loose at least 3 points due to a bug. I had BGP configured correctly but session would not come up, BB was expecting
Quick notes on Zone Based Policy Firewall (ZBFW)
Continuing to check things off from the blueprint. Did some ZBFW labbing today. Here are some important stuff to be aware of. ZBFW is basically a wrapper for CBAC. We create policys between zones and assign interfaces to zones instead
AAA new-model – What does it do?

Frame-relay multilink (MFR) and MLPPPoFR
These topics are probably not very likely to appear at lab but it still good to at least have seen them once so you don’t get stumped if you should get a task like that at the lab. Frame relay
Blueprint – sample frame-relay task
So I’m going through the blueprint checking off everything before the lab. I know FR pretty well by now but there are always some details you forget. As I was going through FR again I thought about possible failure scenarios
Blueprint – Working on my weak areas
So lab is now only some weeks away. This is what I’m up against, the blueprint. The final weeks I will try to go through this list and work on my weaker areas.
Route redistribution – filtering and mitigating loops
This post is about route redistribution and the different filtering techniques we have available in our toolbelt. This post requires that you have a basic understanding of route redistribution. For some good posts look at Petr Lapukhovs posts at INE.
OSPF magic – Make interarea routes become intraarea
This is a follow up post to my last OSPF post about repairing area 0. In the comments section Ray asked me what we can do if we have a scenario where we have another area that is discontigous. In
