So a quick update, I have passed the 400-101 (v5 written) and I’m back into full swing. Thanks to the awesome re-take policy iPexpert offers, my bootcamp is booked also. So if anyone out there plans to attend OWL in March, I’ll be in RTP for that class. All in…

EIGRP OTP – Looking closer part 1
So I’m going to break my closer look at EIGRP Over the Top into a couple smaller posts. Maybe I’ll tie it together with a video when I’m done… maybe lol. So today I thought I’d answer the most basic question of OTP, how the hell does it work?! In…

EIGRP just went… Over the TOP!
So I did a short video with my initial configuration/look at EIGRP OTP. Just thought I’d share it out here as well. I’m going to be looking into it a little more in-depth in the next post, but until then!

New Trouble Ticket — OSPF NSSA and full reachability
So I bumped into a pretty similar task in my studies not too long ago, and decided tonight that it would make for a pretty good blog post. So first things first, here’s our network diagram (sorry it’s not as pretty as usual, but suck it up butter cup). If…

Traffic filtering on Lan-2-Lan VPNs (ASA)
So I know this isn’t my usual R&S blog post… but I continue to see just terribly stupid approaches to filtering traffic across Lan-2-Lan tunnels between ASAs. So this is my small contribution to end the stupidity. Before we get started, lets draw up a super basic diagram to work…

GNS3 IOU Server (GNS3 1.0 Beta 2)
Just thought I’d share this video out from my YouTube channel here also. So the two people who mistakenly read my blog this week can see how this is done. GNS3 IOU Server L2 Image I use — i86bi-linux-l2-ipbasek9-15.1e.bin L3 Image I use — i86bi-linux-l3-adventerprisek9-15.3.1.3T.bin ================================================ Modify this conf file…

DMVPN — MPLS over DMVPN? Oh yeah.
Get your nerd hats on! We’re freaking pushing labels over our DMVPN network, like a boss. As you might have gathered thus far, I’m a little excited. The only downer here is your label switch path has to be hub-to-spoke, so no mas’ spoke-to-spoke tunnels. If you want labels between…

DMVPN – Part 2, BGP with dyanmic neighbors
Oh man… BGP Dynamic Neighbors. This is a freaking cool way of setting up BGP on a device like a Hub router where you’re expecting numerous BGP neighbors. Before dynamic neighbors, I remember configuring my hub router with peer-groups and having an insane amount of syntax since we had ~30-40…

DMVPN — Spoke-to-Spoke Multicast (but why?!)
So now that I’ll off my on-call rotation, I’m getting back to studying. I needed something to fire me, so I started watching DMVPN videos from Cisco Live! 2014. One thing that really sparked my interest was spoke-to-spoke multicast communication. I’ll lead by saying this… not a production solution I’d…

CCIEv5’s DMVPN
First off, fear not. I’ve already recorded videos from DMVPN part 2, I didn’t give up lol. I just need to get some time to toss everything into text format. I just thought I’d do a really short post about DMVPN on the new blueprint. I haven’t tested yet, however from…
