Today I have been going through some more of the INE Vol2 labs and thought I would do a quick post on reflexive ACL’s.

Tonight I have made the plunge and booked a lab date to make my first attempt at the CCIE R&S lab over in Brussels.

Over the past couple of days I have reviewed the remainder of the INE Advanced Technology videos that I felt that I needed to brush up on.

Back when I passed my CCIE written last year I had the momentum behind me and felt that I would be able to study for and take my first attempt at the lab in only a few months.

Before christmas I started my way through the INE Vol1 advanced tech labs and got through the first couple of books, I think I was at RIP.

Sorry for it being a bit quiet over here since the new year, I had a few weeks of on vacation in Disney in Florida and then shortly followed by me moving house so things have been a little hectic to say the least.

Well that one time a year that the entire world grinds to a halt is upon us, yes thats right its Christmas time.

Well all that studying seems to have payed off a little, today I sat the CCIE R&S Written exam (350-001) and passed it!

My next topic for writing up my notes is the security section.

With under a week to go until my CCIE written test it’s time to go over my notes and get some of them written up to get them fresh in my mind.

Earlier today there was an issue raised on one of our new(ish) ME3400 switches that we have started to deploy to customer sites.

I have finally finished my first read through of the CCIE R&S Written OCG and now is time to lab out some of my weaker points, read through a pile of RFC’s and then eventually book and take the exam.

Things have been pretty hectic over the last few weeks/month and so I haven’t had much dedicated study time, sometimes only managing a few pages of the CCIE Cert Guide per day.

Earlier today Network World posted an article regarding a vulnerability that had been discovered in the OSPF (Open Shortest Path First) routing protocol.

Up until now I’ve been hosting this blog under my main website of davidrothera.

Over the past week or so I have been going over FRTS for my CCIE studies.

I have been a little quiet on the blogging front for a while, the reason being I have recently taken on some more responsibilities at work and have also decided to knuckle down and finish my CCIP.

After the last post when I had built up and installed my new Dynamips server along with a set of Sun Quad NIC cards (501-4366, HME or Happy Meal as they are also known) I started to run into some issues.

Back when I first starting studying for my CCNP I built a rack of equipment to lab things up and practice with (picture below) and after completing my CCNP and moving down the CCIE track (after stopping off for a pit-stop at the CCIP station….

If you are having issues with your PIX/ASA firewall (or people believe that there is) there are a couple of checks that you can do just to make sure that the issue isn’t the firewall (as the server guys usually point at the firewall first!

It has been some time since I last updated the blog but that isn’t to say that I haven’t been working/studying away.

I know this is a little off-topic for a Cisco blog but anyway, whilst I am learning some voice stuff I may post something related from time to time.

Earlier today Ivan Pepelnjak over at IOS Hints (url / @ioshints) posted a piece on his blog in which he mentioned the behaviour of MPLS QoS markings and how they don’t copy over upon label imposition at the edge-LSR (the post is here).

Cisco has for some time been using a tool called IOU (IOS on Unix) to be able to simulate configurations for troubleshooting and for testing purposes internally.

I thought I would join every man and his dog and write either a 2010 recap or a 2011 prediction post.
