Re: OER/PfR at lab exam?

Hi Brian,

I haven't seen any updates on this. Did the presentation go ahead? Or are there any updates on when it might go ahead? I'm very interested in attending.

cheers,
Ben.

Subject: Re: OER/PfR at lab exam?

I would be more than happy to do an online presentation covering PfR.
I'm flying to NYC from Dubai tonight for a private CCIE bootcamp next
week and then I have a public bootcamp in Washington DC after that so
next weekend I'll be available. So if you all can be flexible we can
try for next weekend. We can use our new streaming solution so that
it's all recorded in a format that everyone can download and view for
the people who can't attend.

How about this.... Someone (expert) on the subject of OER put together a webex and let it roll.. I'm willing to sacrifice a Saturday and a little $ to get it rolling.
It seems a lot of people are lacking confidence in the OER realm, including me...  So what do you say?

Since PfR/OER is relatively new to the lab exam it's not covered as much
as a topic like OSPF, MPLS VPNs, etc in most products.  That being said I
currently spend at least one full day covering it in my 10 Day R&S
bootcamps and I cover it in-depth as getting 5 or 6 points on it in the lab
exam can be the difference between passing or failing.  I start from the
basics (i.e. load balancing, PfR static&  BGP route manipulation, etc ) and
work into the more advanced configurations (i.e. link groups, fast mode,
jitter probes, delay, PBR based upon DSCP, using PfR for sink holing
traffic, etc).
To be honest there are a ton of strange, for lack of a better term, quirks
with PfR that can cause trouble when someone is just starting out learning
PfR.  So although it may seem like a good idea for me to just throwing you
the labs from my bootcamp, that isn't going to be what you really need to
truly understand it.  It would be like saying to me "Hey Brian I want to
learn MPLS VPNs" and I say "Here are a couple labs. Good luck!".  Think
that will work?  No.
Here is just a few example of quirks with PfR:  An access-list used with a
learn list can not match IP addresses but an access-list with a oer-map
should match IP addresses.  When using fast mode with a learn list you need
to use a prefix list when also matching with an access-list.  Or how to
configure PfR to do PBR unconditionally without any OOP condition, etc,
etc, etc.
As I mentioned there are a lot of pitfalls with learning PfR due to the
fact it's a newer technology and went through a lot of changes in IOS
12.4T.  PfR is an awesome technology and I personally love it but it can be
complicated to learn for anyone starting out.  I would venture to say that
is it one of the most complicated of any technology currently covered in
the lab exam.  The documentation is 33% bigger than the OSPF documentation
and it's only getting larger with QoS being added and PfR domains in future
releases.
I started a blog series on it (http://goo.gl/yH0ip) but have since
decided to just write a whole document covering PfR as the topic is just
too big to cover in a few blog posts.  I currently have over 100 pages and
I'm hoping to release it around the end of the month.  If anyone would like
a copy, free of charge of course, just let me know.
Lastly if anyone wants to come see me cover PfR in person free of charge
just contact INE sales and ask to audit one day of my bootcamp.  It's
normally covered on the 8th day of my bootcamp.  I'm in Dubai this week and
covered PfR yesterday and have a private bootcamp next week but after that
I'm teaching in Washington, DC and Seattle next so feel free to stop by.

Hi,
I just purchased ciscopress ccie r&s exam cert guide 4th edition,
since I had 3rd in which there was nothing about OER and PfR. I must
say that the quality of that subject in new edition of the book is
really poor. One config example without any explanations and without
any topology diagrams. Nothing that can help someone to understand the
topic.
So, my question is how deep this subject goes in potential task at
exam? How much time should I spend on it since it can be very complex
feature? The book says:
"As you will see as you explore PfR more deeply, it is remarkably
powerful. As you would expect, it also has many configuration options.
For the CCIE R&S qualifying exam, you should understand the concepts
of PfR and how it operates and its core functionality."
Thanks.
