Wendell Odom Has Spoken!
Filed Under CCIE General
So way back in June when I was studying the R/S exam cert guide 3rd edition for the written exam, I found what I thought was an incorrect answer. Feeling more motivated and inspired than usual that day, I actually wrote in to the email address in the book for errata and kind of forgot about it. This morning I received this email from Wendell Odom himself!
Hello Joe,
Wendell Odom here, co-author of the CCIE R/S Written Exam Cert Guide from Cisco Press. You had sent in a note about an error in the book way back in July. My apologies for the delay in responding; the delay was my fault. However, just in case you still care about a response, I wanted to give you my thoughts.
Here’s what you wrote:
I believe the answer to chapter 8, question 8 of the “Do I
know this already” quiz is incorrect.
In the answers appendix the author states “…Because it is passive, no
hellos are sent out fa0/0, meaning no neighbor relationships are formed,
and no routes are exchanged either in or out fa0/0″
However, the correct answer, listed as “C” states “R11 will advertise
subnets 10.1.1.0/24 and 10.1.2.0/24, as well as attempt to send hellos
and updates on the related interfaces”
Why would it attempt to send hellos and updates on 10.1.1.0/24 if it was
configured as a passive interface as shown in the configuration for the
question?
You are indeed 100% correct. The question is wrong. In short, R11 wil advert about 10.1.1.0/24, 10.1.2.0/24, and 10.1.3.0/24, and only send Hellos on the interfaces connected to subnets 2 and 3. So, the explanation text in the answer appendix is accurate, but the answer C text back in Chapter 8 is wrong.
Again, my apologies for the delay.
Regards,
Wendell Odom
Sure it’s really no big deal…I mean it is an obvious mistake, but I have to tell you…Wendell Odom contacting me at all, let alone Wendell Odom contacting me to say “you were right” felt pretty damn good! It was like GOD stepped down for a second and said “Hey good job!” haha

Ya know..I have to give those authors some credit. I actually contacted Jeff Doyle through his blog once and asked for some suggestions for some material while working on my CCIP. I didn’t really expect a response to such a little question, but I had an email back from him in a couple of days.
I try to follow both Wendell’s and Jeff’s blogs, and I think they both seem really good about responding to people, especially when they have questions.
Wendell Odom i know would reply but might take time.when i was doing my ccna, i sent him a mail and he did respond
Nice! Maybe there is still a chance he will reply back to me about a couple of things that I thought were unclear or erroneous in his book back when I was still studying for CCNA.
But then again I’ve been trying to listen to God’s voice for a long time now and I still don’t know what he sounds like.
hey, I even sent a mail to Scott Morris (Quadruple CCIE) and got a quick response from him!
as you already said : felt pretty damn good!
Scott Morris is pretty good replying to emails. You have to commend the guy for how busy I am sure he always is to respond as much as he does in groupstudy as well.
