Life Update
I haven't been posting as much as I would like to, but I have been super busy. Some crazy events unfolded in my life which sucks, but there is some great news. I have quit my job at an MSP and I will get to start my new
Short - Cisco SD-WAN
Cisco SD-WAN is an enterprise grade WAN architecture overlay that enables digital and cloud transformation for enterprises. It integrates routing, security, centralized policy, and orchestration into large-scale networks. Here are some benefits of Cisco SD-WAN: Centralized network and policy management, seamless connectivity into the public cloud, optimization of SaaS applications,
Components on SD-ACCESS
Cisco Software-Defined Access is driving evolution for normal campus network designs. It is a software application that is used to automate wired and wireless campus networks. There are many benefits to deploying SD-Access, some of these being: simplified deployment and automation, network assurance, consistent wired and wireless security capabilities, etc.
Distance Vector vs Link State vs Hybrid / Advanced Distance Vector Routing Protocols.
The purpose of link-state and distance vector routing protocols is to help transmit traffic across a network as efficiently as possible. Think of this as something similar to going on a road trip. If you are going on a road trip, you probably would plan out the best route to
Certificate Authorities
A certificate authority is a trusted organization that issues digital certificates to websites, businesses, and also individuals. When a CA issues an SSL certificate, it verifies the website domain and the organization behind it. This helps validate the trust between users and the website, ensuring that sensitive data is able
CRC
Over the weekend I ended up taking both ENSLD and my Palo Alto NGFW engineer exam. I originally thought I would pass ENSLD and fail my Palo Alto certification, but it was the other way around. I realized during my testing for ENSLD there was some stuff I forgot because
DNS IN DEPTH
It has been a while since I have posted on here. It has been a crazy busy week and a half, and I have two big exams coming up on Friday. I am taking CCNP ENSLD for my third CCNP and the Palo Alto NGFW engineer exam. I am confident
SSL
SSL, also known as Secure Sockets Layer, is an encryption-based internet security protocol. The purpose of it is to ensure privacy, authentication, and data integrity in internet communication. This is the predecessor to TLS encryption, which is used today. So how does it work? SSL encrypts data that is transmitted
TCP VS UDP!
Back to the basics with this one. These are two core protocols in networking, they are used for sending data over the internet and other networks. TCP stands for Transmission Control Protocol and is used for reliable connections. UDP stands for User Datagram Protocol and it is used for fast
Studying Techniques
Studying is tedious, it can be boring at times, hard to focus, etc. It's easy to get distracted by Instagram reels, TikTok's, YouTube, and more. I wanted to give out my study techniques I use that personally work for me and I hope they can be
Enterprise Network Campus Design
I wanted to take a break from the multicast as I have been writing a lot about it lately and studying it. Today I want to dive into enterprise network campus design. I also want to mention that in future blogs I might start adding lab examples. Right now my
Auto-RP and BSR
Sparse mode requires an RP for a meeting point in the network for all multicast traffic. This can be manually configured, but that becomes tedious when dealing with many devices. This is where Auto-RP and BSR become useful. Auto-RP is a Cisco proprietary protocol, and it involves two roles: the
