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…

DMVPN – Part 1, it’s not that bad.
So I wanted to do a couple posts on DMVPN, one of the new topics to CCIE v5. I’ll run through a basic setup in this post, with a video at the end. In the next few posts I’ll show some of the more advanced things we can do with…

Lab Hard, with a Vengeance (VPLS in GNS3!!)
So I’m finally getting back into lab mode, and getting excited out R/S technologies again. After realizing that the requirements for Cisco’s CSR1000v (Cloud Services Router) has been dramatically decreased I wanted to get one into virtualbox and throw it in the mix with GNS3. The results thus far have…
