What Next?
Hi Everyone! (Wonder if anyone still reads this blog)
This is my first post after a long hiatus from blogging.
Its been four months since my Last major exam. I decided to take a very long break since the exam was very demanding and I had to make up for 'other parts of my life' that suffered while trying to obtain my second CCIE.
Now, Its time to answer the million dollar question: WHAT NEXT?
At 21, with 2 CCIEs, I have just completed my year of 'compulsory' service to my country (finally), and its time to make a major career decision.
Options?
1. Pursue an academic (technical) degree: A Masters in Engineering or some related course looks appealing (the perfect icing on the cake for the Bachelors) but just doesn't seem to fit in the grand career plan at the moment. I do not see the relative advantage that a masters degree would offer me at the moment, so I'll pass.
2. Pursue an MBA: A masters in Business Administration might expose me to the right business knowledge that would complement my technical skills but I dont think this is the right time for an MBA, I'm a techie at heart and I still love what I do. Maybe in the next 2 years but definitely not now.
3. More CCIEs: I have been toying with the idea of taking another CCIE in SP or Voice. The challenge and the knowledge that comes with the CCIE study process is just too much fun to ignore. But if I have to do any more CCIEs, I need to have the experience to back it up, so I would wait for a few months before I launch out.
4. CCDE: The CCDE exam intrigues me because of it acclaimed difficulty, some part of me wants to study for the exam while the other part is certain that the exam is not meant for mere mortals like me. After looking at Petr Lapukhov's recommended list of materials, I have decided that I would pass. That would take a few years to study :)
5. Nothing :)
Conclusion: I do not think I would be taking any milestone exams in the next few months. I would rather focus on getting enough experience and building my project profile. This might involve changing job-roles, changing organizations or even location as long as the goal is accomplished.
Please feel free to drop your comments, I actually need them :)
Hope to post some more (non-techie) stuff soon.
Cheers!

It is done...Security Lab Passed!
Hi All,
I passed the security lab yesterday in Lagos (mobile lab) on my first attempt.
Thanks to everyone that was a part of this journey.
1. God: For grace, strength, courage, provision and favour.
2. Family: For all the support. Thanks a million.
3. Friends: You guys are the best. It's not easy to have so many friends when all you do is sit and stare at a screen all day.
4. Study Partners: (Tacack, Deolu, Peter) It was fun studying with you guys. Wishing Peter all the best as he takes the lab today!
5. Study groups: OSL totally rocks. Groupstudy, CLND and IEOC are also very helpful.
6. Everyone that wished me Luck :)
Study Materials
I used INE study materials (because I fell in love with them since my R&S) and they are very good. IPExpert also has some quality materials too. Yusuf's labs are also incredible and they show you what to look out for in the lab.
Once again, thanks for everything.
Cheers,
Amplebrain, CCIE R&S and Sec

7 wishes for 21
Its exactly 7 days to my 21st, and I am very excited. I am trying to make a wish list and I am finding it so hard (I'm just not used to making wishes :)
Anyway, here's my list - Just 7 items.
7. A smartphone: I'ld like a device that would keep me away from my laptop. I spend approximately 16hrs with *her* per day.
6. A PhotoAlbum: Yes, I intend to keep one :-)
5. A book - I can never omit this. Learning is what keeps me alive :) I'ld let you choose the kind of book :)
4. A transition ceremony: I personally consider 21 as the full transition to adulthood. I'ld like to celebrate this transition in a special way :)
3. A sincere opportunity to give back: All my life, I have experienced divine and human help in all my endeavors. I believe in paying-it-forward so I am looking for a *sincere* opportunity to give back in the little way I can.
2. A special gift in exactly 21days from now :)
1. A gift from the maker: Something special from the one who started me on this journey and has kept me for the past 2 decades.
That's it :-)
Cheers!

GETVPN With Multicast Rekeying
Hi All,
A post by fellow CCIE-Sec Candidate TacAck made me do some research/revision on GETVPN Rekey. I would highlight my findings in this post.
1. There are 2 modes: Unicast and Multicast.
2. The Rekey address command references an access-list that is downloaded to the group members which makes them automatically join the group (for multicast Rekeying)
3. With Rekey Authentication, The crypto keys must be generated
4. Rekey is triggered by changing the SA access-list. Rekeys are retransmitted for a number of times n after a period p. This can be adjusted with the "rekey retransmit p n" command
Here is a sample config for the KS:
crypto isakmp policy 10
encr 3des
hash md5
authentication pre-share
crypto isakmp key CISCO address 192.168.123.1
crypto isakmp key CISCO address 192.168.123.2
crypto ipsec transform-set TRANS esp-3des esp-md5-hmac
crypto ipsec profile GET
set transform-set TRANS
crypto gdoi group GET
identity number 123
server local
rekey address ipv4 REKEY
rekey retransmit 10 number 2
rekey authentication mypubkey rsa GET
sa ipsec 1
profile GET
match address ipv4 GET
replay counter window-size 64
address ipv4 192.168.32.3
ip access-list ext REKEY
permit udp host 192.168.32.3 ho 239.0.0.1

5. If an ASA is placed in between the KS and the GMs; two things must be considered.
1. Allowing GETVPN traffic especially if GMs are outside since the GM initiate the registration process. A hole should be punched to allow udp destination 848
2. Multicast traffic should be forwarded by the ASA. If the GMs are directly connected as in a STUB, then the "igmp forward" should be enough to forward the traffic.
Nuff said, time to take a break :)

My Favorite RFC
Hi,
I have had to review several RFCs in the course of preparing for the security CCIE. Common ones include RFC 1918, 2827, 3704 and 3330 which are on the test. Other Fun RFCs include 2385, 3715, 3945 and 3947.
Today, I stumbled on what I would call my favorite RFC 1882 - 12 Days of technology before Christmas. This is a classic geeky joke. :D
Enjoy!
Cheers, Amplebrain
