So most if not all RS candidates have at least heard if not used Ruhann’s routing bits handbook. I used it whilst studying during R&S and am so happy that Ruhann has released a companion version for the SP track. Up until now he has hinted at its release but nothing has come out until today, if you head over to his blog here you can download a free sample of the upcoming SP handbook for free. Although it is geared towards candidates that are going for their CCIE I…
So this week my CCIE package arrived along with this little beauty. I had no idea these things weighed so much, mind you I suppose for $1500 its what you should expect I’m currently on with studying for the SP, all good so far as a lot of it is very familiar due to my day job but there are still a fair few new things to learn before I make an attempt. Perhaps try and make a lab attempt by the end of the year? I guess we will…
The other day whilst reading up on some SP topics I came across a rarely used function available on some higher end Cisco models called half duplex VRF’s (or HD VRF’s in some places).
I know it is quite a common thing to see in service provider topologies where you have a radius / virtual-template driven platform such as a DSL LNS etc but up until now I wasn’t aware that it can also be used on other platforms on regular (non virtual) interfaces.
For the demo topology I am going to use a faily simple network of three 7200′s in GNS3. According to the Cisco documentation here this feature has been around since 12.4(20)T or 12.2(33)SRC for the SR train.
In the topolgy I am using R1 and R2 to emulate customer sites which will be a member of the same VRF on R3 which will play the role of our PE.
A post over at the IEOC forums got me thinking to something I picked up a long time ago but I can’t really remember where…
When a prefix arrives at a device from two different sources the AD is compared and the lower AD wins out, simple CCNA level stuff right? Well what if the AD is the same due to AD manipulation?
Well I’ve decided to take on the CCIE SP next. Given that there is a lot of overlap between the two tracks and that I use a lot of the technology (multicast aside) in my day job it should be quite good. I’ve started as I did with the R&S by going through the INE ATC videos and have been going over IS-IS tonight, it’s something that is new to me as by the time I did the CCNP it had been removed so its my first time on the…
Well since passing my CCIE R&S I’ve been sat at the crossroads of where to go to next.
I have multiple things that I’m interested in doing:
- CCIE SP
- CCIE DC
- CCDA / CCDP
I think I’m going to go for the SP track next, it makes the most sense in what I do day-to-day but at the same time some of the new DC technologies are pretty interesting.
As a follow up to my last post here on my CCIE lab failure… or so I thought. Those of you who have read through the post will remember that I couldn’t really see where I had gone wrong, if you would have put me in the same exam again I would end up doing the exact same thing again and this kind of bummed me out and made me doubt myself! When I got my score report and saw that I scored a 43% on Layer2 I thought something…
Well since getting the result of my 3rd lab attempt (FAIL for those that haven’t already seen) I’ve spent the rest of the week getting on with my normal day-to-day but also considering where did I go wrong? On both my first and second attempt I felt OK but I had known there were weak points that I could lose out on; the first attempt I ran out of time and didn’t check any task through and on the second I had to skip one of the big TS tickets,…
I’ve been quiet on here since my last attempt but yesterday I once again made the trip to the Lab in Brussels…. and once again have come back empty handed. Unlike my first two attempts I felt secure with this attempt, my troubleshooting went well and all tickets were completed and the configuration was sailed through with more than enough time to triple check everything and even reboot all the kit and check it again. Someone said before that you never really fail until you give up but this time…
What do you mean I don’t get anything for a full set? Unfortunately I got the results of yesterdays CCIE attempt and much like the first it was a failure. The result came in a little quicker and arrived whilst I was on my flight back to the UK. Where the failure differs is that this time I passed the config section (which I failed the first time) but failed the troubleshooting (which I passed last time) and unfortunately you don’t get anything for a full set I can’t say…
