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
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
PIM Sparse Mode To start off, we have PIM Sparse Mode. In sparse mode, we don’t forward any multicast traffic unless someone actually requests it. So when a host wants multicast traffic, how does it know where to get it from? That’s where something called an RP (Rendezvous
As I stated in the last post, there are three versions of IGMP. These are V1, V2, and V3. So what are the differences? I will be explaining that, and I also want to just quickly go over what IGMP is. IGMP is when a host tells a router that
Multicast is a way we can send traffic. Just like unicast (one to one), broadcast (one source to everyone), and then we have multicast. Multicast is one to many, not everyone. This means we are able to send traffic to a group of receivers. Why would we ever want to
For a lot of people QoS is a very hard concept to grasp and understand. This is understandable as there is a lot that goes into it and a lot to learn. In this post I want to go over the different types of QoS Models. There are three main
When I first learned about this topic when studying for ENSLD it was very hard for me to understand. I'm not sure why, it just hurt my head to learn about so I am going to explain it after doing research into all of these migration techniques and
There are a lot of ways you can manage and configure your Palo Alto firewalls. The 4 ways are: Web interface, CLI, Panorama, and XML API. This is a topic on the Palo Alto NGFW Engineer exam I will be taking next month. Here are how you can use them:
OMP, overlay management protocol, is a TCP based protocol which is responsible for establishing and maintaining the SD-WAN control plane. It helps us exchange routing information, policy information, and also management information between vSmart controllers and the vEdge routers in your network. There is no need to enable this on
Cisco SD-WAN is a very popular product. The reason for this is because buying private wan connections like MPLS are expensive. People want a cheaper solution. This is where solutions like SD-WAN come into play. SD-WAN is able to save us money by using a combination of internet and private
I've been studying for my PCNSA from Palo Alto and one topic that has been brought up in types of administrators. By default when you first set up a Palo Alto firewall there is only one default admin account. This is not a good practice especially when there
I'm starting to dive into the world of ISE because I may potentially have a project involving deploy DNAC and ISE soon. To get better at this I wanted to actually use it and try it out. I don't have an ESXI license (Thanks Broadcom!) The
