This Bridge is the Root

If you've ever watched a GlobalProtect client connect to an unexpected gateway and wondered why, this post is for you.

I have a client that is currently in the process of migrating their network to IPv6.

Recently, at Cisco Live 2024, I passed the Cisco ENCOR exam to try and re-earn my CCNP certification that I unfortunately let expire.

Enhanced Interior Gateway Routing Protocol (EIGRP) is a dynamic routing protocol widely used in computer networks.

I’ve been fortunate enough to be given the opportunity to go to Cisco Live US twice in my career (2024 will be my third!)

With a plethora of address configuration options available, it's essential to understand the nuances of each method.

Suppose you had a problem, you want to use a provider assigned globally unique IPv6 address space for your network’s clients and you’d like to do this as dynamically as possible because either you can’t guarantee that the provider won’t change the address…

The IPv6 header format made some radical changes away from the relative complexity of the IPv4 header.

OSPF is one of the most ubiquitous interior routing protocols in use today.

Consumer VPNs have become increasingly popular in recent years as individuals seek to protect their privacy and security while browsing the internet.

Cyberattacks are constantly evolving and becoming more sophisticated but UDP amplification attacks are relatively simple ways for attackers to leverage your resources for their gain.

I was recently consulting with a client and the network architecture we were proposing drastically increased their ability to deploy network segmentation.

I’ve held the opinion for a while that if you’re not occasionally causing outages, you’re not doing any work.

The BGP Best Path Selection algorithm can be a tricky thing to wrap your head around.

In computer networking, few commands are as powerful and directly impactful to the functionality of a network as a static route.

IPv6 has been perpetually just over the horizon because the naysayers claim it's too hard to implement, IPv4 is ‘good enough’, and there are no 'killer apps'.

In a recent project, we were deploying entire sites using DNA Center Templates.

Cisco built Plug and Play (PnP for short) into DNA Center as a way to easily onboard new devices without a configuration to be used either with the templating engine or with the SD-Access architecture.

MacBook Pro I run a 2018 15 MacBook Pro as my primary laptop.

When I started this blog back in January of this year, I did it to share my knowledge, to prove to myself that I could stick with a personal project in the face of a hectic work schedule, and to better myself by forcing myself to learn new things and impr…
