From the show commands, the problem is that Router B has a physical problem that is causing it to receive low or no power from the device its connecting to on interface TenG 0/0/0/0. In which case there will be a need to check that particular connection.

Worldcup 2014


For me this World Cup has been very entertaining. At first I thought I would not watch many matches because most matches were to be played from 11PM.

Contrary to that I have watched almost all the matches and have thoroughly enjoyed this.With Super Sport = Brazil, this has been a treat. I liked that advert a lot.

https://www.youtube.com/watch?v=xeVIOlmiwKo couldn't get the Africa supports Africa one but that was very good too.

 I was hoping that the Netherlands, France would go further than they did. I hope they learnt their lessons and will be better in future tournaments.

African teams did us proud in many ways, especially the Algerian team which almost beat Germany. Ghana and Nigeria were also good but were very very unlucky not to have gotten past the groups stages.

Worst team from Africa Award?  This definitely goes to the Cameroonian team. Lack of cohesion.. how do you end your worldcup preparations with a STRIKE? I think its time for the old boys from the team to retire from the national team. Whatever they did was almost equal to what the French did iin South Africa.

Spain? It was humiliating fr the defending champions to go home that early. This is a team that also needs to get rid of the old boys and build the team around the youngsters who have won youth championships. That might be their best bet. Donate that Costa guy back to Brazil. His injury plus failure to jell in may also have played a part in the dismal performance.

Harambee Stars?

Hooray. for the first time ever the Kenyan team made it to the World Cup thanks to our president. Next time we hope that they actually get to go to the World Cup as a participating team.

As much as  have always like Argentina, I don't see them winning the game tomorrow against Germany as the Germans have more flair at the moment. The 7-1 demolition of Brazil must have given them a confidence boost.

Whose gonna be the top goal scorer? I would prefer James Rodriguez to get the Golden Boot award. The passion he had, plus his easy touch on the ball was exquisite.

As for the 3rd place match today, nobody really cares. This is a match for losers. There is no point playing this match.. as LVG stated.

>> Lets see how this winds up and look forward to the EPL which amazingly is  attracting talent from all the other leagues. With a new managet Man U is bound to perform better.

My CCIE Journey

I am currently trying to beat the deadline for the CCIE R&S exam. Cisco is moving from version 4 to version 5. As I have been reading the version 4 material for sometime, I would prefer to do the version 4 exam and then plan for the lab later.

Cisco has made important changes in version 5 which includes removing frame relay (this archaic technology) which was the thing when TKL was still the biggest player in the ISP business in Kenya :). This reminds me of what one Bryon said last week - Evolve or die, clearly TKL had it rough because they didn't evolve but lucky for them.. they didn't die.

I have been through most of the topics, after going through video material, I have decided to go back to the official Cisco R & S Certification Guide. Then I will get back to the video's.

I am currently on Chapter 6: IP Forwarding (Routing).. though I am not reading this stuff systematically. My base is BGP & MPLS being the topics that I interact with the most in my day to day job since the time I joined a local ISP's NOC.

I am a CCNP R&S by the way..

Lets see how it goes.. I was telling a friend that this certification is worth like 90,000 USD per year. Hope that''s the case or better by the time I am through ..

Wife's Grandmother dies..

It's the 08/03/2014. Women's day and am at work. About 2 hours ago I got a call from my wife and she could hardly talk and disconnected the call. At first I thought she was laughing and she had called my by mistake. When I called her back she was sobbing and I knew something was wrong even before she uttered a word.

We had planned to call her aunt in India to get to know how my wife's grandmother was fairing on yesterday, as this didn't happen, I reminded her to make the call in the morning as I was leaving for work. I called her again after I had worked for about  two hours to know how she and the baby were. She informed me that the baby was Ok and she was to call her aunt.

The grandmother had been taken to India for surgery as she had a growth in her abdomen. The operation was successful .. I am not sure what went wrong. All the same she had lived a good life, was a good mother and grandmother. Someone loved by many. She was an active christian at the Naikuru PAG church.

She is a woman who I knew for about two years but loved very much because of her charisma, attitude and hospitality.

May she rest in peace. We loved her but God loved her more.
