Cisco Live 2014: Dipping my Toes into the Social Side of Cisco Live

Trying out the Social Side this Year
Submitted by Denise Fishburne on Sat, 04/12/14 - 7:05pm.

New to CiscoLive? At some point we all were there.  The mixture of emotions, of course, is different for everyone.  For me?  Crazy excitement coupled with a huge dose of adrenalin and fear.

Why? Not only was Networkers 2006 going to be my first time ever going, I was going to be presenting.

2014: The year of IPv6

IPv6: Learn It, Live It, Love It
Submitted by Denise Fishburne on Tue, 02/25/14 - 4:54pm.

IPv6 is #1, #2, and #3 on my technical "to do list" for 2014.  This is, for me, the year for IPv6.  

 

 

 

 

 

 

 

Why IPv6 when there are so very many "exciting buzzward acronyms" out there right now? Because it is time.

Cisco Live Distinguished Speaker Hall of Fame: First Female Inductee

Shelly Cadora Inducted into "Hall of Fame"
Submitted by Denise Fishburne on Mon, 08/26/13 - 2:31pm.

“The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires.” 

~William Arthur Ward

Shelly is one of those "great teachers that inspire"!!   Truth be told I would never have known what a great speaker she is had I not seen the announcement of her as an inductee into the Distinguished Speaker Hall of Fame.  She makes the complex seemlingly simple.  What an incredible gift she has!  I have now watched one of her sessions 2 times already!  (More on that later)

Clearing Up Some Misinformation RE: eBGP Multihop and TTL

Myth: You have to set ttl to 2 because it is decremented on the way to the loopback.
Submitted by Denise Fishburne on Sun, 06/30/13 - 10:39pm.

Last week I was at Cisco Live in Orlando and met, yet again, some people that had been taught one must set the TTL to 2 for two directly connected routers to be able to eBGP peer between their loopbacks because the TTL "gets decremented on the way to the loopback." The web, ya gotta love it. When I try to help someone deprogram this brain washing, I find pictures help. So for those who'd like to get deprogrammed, it's time to play!

Every Network Failure Should Be Used to Improve the Network

Some advice for rebounding from network failure.
Submitted by Denise Fishburne on Wed, 06/12/13 - 2:35pm.

Let's accept reality. A network is so much more than just the sum of its electronic parts, operating systems, and configurations. It is an extension of the past and the present of our company. Much like the growth rings of a tree, we can look at our company's network and see all the human history of our company.

Cisco Overlay Transport Virtualization (OTV): A Little Fun in the Lab

Sniff a VMware vMotion happening over OTV.
Submitted by Denise Fishburne on Sun, 06/02/13 - 11:09pm.

Recently, I’ve done a few labs with OTV in them. Each time, however, I had an OTV SME (subject matter expert) in the lab with me. They configured it and it just “worked magically." No hiccups. No gotchas.

Wireshark Certified Network Analyst: Taking my Wireshark Knowledge to the 'Next Level'

Wireshark is hands down, bar-none, my absolute favorite tool for network "forensics," troubleshooting, and learning. I used to think I was fairly good at it. But WOW was I living on the "tip of the iceberg!"
Submitted by Denise Fishburne on Sun, 11/25/12 - 2:36pm.

It all started a little over two years ago. I was doing my usual "Cisco Lab Rat" type job and had some customers in the room. There was a concept I was trying to explain so I did a quick sniffer capture and then used Wireshark to help me show what was actually happening "on the wire" between the two routers. Armed with my sniffer trace and the concept that "a picture is worth a thousand words," I called them over.

Bidirectional Forwarding Detection (BFD) – A Little About Timers

Instead of lowering and lowering IGP timers... maybe it is time to think outside the box.
Submitted by Denise Fishburne on Mon, 06/25/12 - 9:31pm.

Two weeks ago I taught Routed Fast Convergence and High Availabilty at CiscoLive US in SanDiego.  it always surprises me how few hands get raised when I ask how many people know about BFD.  With BFD OTV coming out… and BFD MPLS options already available… and support of BFD with NSF/GR on some platforms…. and BFD with SVIs..... I've decided it was time to take my knowledge to the “next level” in preparation.  And, I might as well bring y'all along for the fun.  This post and my last post are to lay some necessary BFD ground work.

Bidirectional Forwarding Detection (BFD) – A Beginning and an Introduction.......

Instead of lowering and lowering IGP timers... maybe it is time to think outside the box.
Submitted by Denise Fishburne on Fri, 06/22/12 - 11:40pm.

What is Bidirectional Forwarding Detection (BFD)? Why learn about it?  Why use it?  ..... This article is going to be a "beginning"... an "introduction" into Bidirectional Forwarding Detection.  First we will look at what it is and also look at the most "simple" use case for it that I know of.  Then we will config it on a 7600 and an Nexus 7K and watch them neighbor up.

Decision Making Time! - CiscoLive 2012

What classes do I want to take this year? LISP? IPv6? Multicast? FabricPath? SDN? SBA?
Submitted by Denise Fishburne on Thu, 04/19/12 - 8:04pm.

First, I have to lead off saying that I LOVE CiscoLive!!  

Yes, I work at Cisco...... Yes, I am a speaker at CiscoLive...... Yes, I'm even a Session General Manager for session groups RST (routing and switching) and IPM (multicast).   So this might all just sound like me just "drinking the kool-aid" or "marketing" CiscoLive to you.  But that is honestly not it.

Understanding the BGP Table Version - Part 2: More Introduction to BGP Table Version

More on BGP Table Version – the most unknown, unexplained, unloved, and unused BGP concept/value that I rarely ever troubleshoot without

This is the 2nd post in the 3 part series of "Understanding the BGP Table Version".  Please visit http://www.networkworld.com/community/node/80089 to review part 1.  

Last we left our network, we had the below 3 routers and a BGP table version of 4 in Router10.

Understanding the BGP Table Version - Part 1: Introduction to BGP Table Version

BGP Table Version – the most unknown, unexplained, unloved, and unused BGP concept/value that I rarely ever troubleshoot without.
Submitted by Denise Fishburne on Tue, 03/20/12 - 5:47pm.

I cannot honestly imagine troubleshooting BGP without understanding the BGP table version.  I use it all the time.  Sometimes it is just a quick "eyeballing" of it to check to see if all the BGP table versions are in sync.... or if there is work to be done.  I see people "eyeballing" the up/down time for a BGP peer when they are troubleshooting.  And sometimes I see them quickly eyeball the InQ/OutQ columns.  But I rarely ever see anyone using the BGP table version.

"Uh ... Err ... Hi again. It's me. So ... uh ... how's it going? What have you been up to? Err ... umm ..."

Ever had one of those times in your life that you just don't know what to say to a friend? You told them you would do something (call, write, return a call, keep in touch, call more often) but you don’t.  And then time passes.  And you think to yourself… "Man, I have to fix this."  But you don't.  And more time passes.  Now it is just awkward!
