Lately we have been looking at various automation topics like Python where we can do some configuration or grab some output on a few boxes. Today we are going to kick the tires with Cisco’s Embedded Event Manager (EEM), the neat difference with this feature is that it runs directly on the Cisco device so it can run based on events like a command being entered or the router getting a new CDP neighbor.

I’m Watching You – An IP SLA PostStandard
I wrote this for the CCNA sub but might as well share it here a well
Since everyone loves Infrastructure topics (right?!?!?) lets play with a neat feature on the R&S exam called IP SLA. I figure I might highlight some of the more overlooked topics in this sub.

Mobile Command – A SDN PostStandard
My my, I’ve been meaning to make a few SDN posts for ages! Fortunately my golf game got cancelled today and I figured it was finally time to get this started.
A Tale of Two VPNsStandard
Since I still have my ASA lab up, let’s play with two types of VPNs.
That other other routing protocol – ODRStandard
So now we talked about a somewhat more specialized routing protocol, let’s talk about a protocol that probably only a few of you would know about here.
On Demand Routing!
That other routing protocol – A IS-IS PrimerStandard
Today we’ll be playing around with the routing protocol that never seems to get much R&S certification love out outside of the written and the SP track, IS-IS!
A Private VLAN PrimerStandard
Hi CCNA Security Gang,
Since VIRL now supports private vlans, let’s do a private vlan post since it seems to be confuse a lot of people.
The Router that thought it was an ASAStandard
There seems be a lot of people interested in CCNA Security so let’s have a brief look at Zone Based Firewalls.
Fun with Linux – Quagga RoutingStandard
In this post I’ll be looking at using CumulusVX to doing some routing with a Cisco router, why Cumulus? It is a great Linux distribution / virtual switch that has a strong Quagga implementation.
Fun with Windows – BGP RoutingStandard
Need a another router for your BGP lab and can’t be annoyed to create another router in VIRL/GNS3 or plug in another router for your lab? Never ~feel~ fear, use Windows instead!
You Shall Not Pass – ISE TACACS+Standard
I recently rebuilt my ISE lab to play with 2.2 and figured I may as well do some security posts while I’m at it. Today we’ll briefly dip our toes in the water by playing with TACACS+’s Command Authorization.
VPN Wizardry – Anyconnect Multi ProfilesStandard
Here is a quickie but a goodie if you work with Anyconnect. Anyconnect only remembers the last connection which can get very annoying if you are like me and have to connect many different VPNs throughout the day.
Breaking In – Fun with the Native VlanStandard
Since I’m still in security mode until I can get my massive SDN post completed, lets have a look at using Yersinia to have some fun with native vlans and DTP to remind everyone DON’T USE VLAN 1!!!!
Back to the Basics – Pipe DreamsStandard
To finish off our fun with show commands series, likes look at one of my favourite tools, the pipe command!
Back to the Basics – Fun with the Routing TableStandard
Just for some Friday night fun….
Let’s look into some of the options that are available in the
show ip route command that everyone may not be aware of.
Back to the Basics – Showing Run like a ProStandard
Continuing the theme of showing what show commands can do, let’s look at
show run for a bit.
Breaking In – Fun with SNMPStandard
Well as luck will have it I won one of those CCNA CyberOps scholarships and it starts….September…of next year…thanks Cisco! So since I haven’t managed to publish anything in a while, here is a entry I did for Reddit’s CCNA sub.
Head in the Clouds – Bridging FunStandard
Today we’re going to play with bridging!!! Why are we talking about bridging in 2016 you ask? Well because I’m going to making a few posts as I work my way through the CCNP Cloud certification as well as catching myself up on the new CCIE DC blueprint so I’ll be talking a lot about VXLANs for a least a couple posts. Since bridging is making a come back in L2VPNs and such I figured why not start here? Also I just want to write about something that doesn’t need 50 screenshots 🙂
Checkpoint – The Gentle SIC ResetStandard
I found myself in a awkward situation the other weekend where I lost access to Check Point’s internal networks after switching over some networks due to anti-spoofing and after a short adventure of spinning up a new management server in Azure, pointing the firewall to it and pushing a more permissive rule I was back online!!!!
However the problem now was that if I reset the SIC to point it back to the old mgmt station it would do a CPSTOP and CPSTART which would unload the happy policy and I would be back offline and no I could not go onsite!
