Before configuring our environment, we need a foundation or understanding of how multicast works. It is such a massive topic
In our last post, we talked about OSPF Basics. Today, we will look at what Virtual eXtensible Local Area Networks or VxLAN are. VxLAN is an overlay technology. It can transport Ethernet (Layer 2) over IP (Layer 3). Typically deployed in larger data centers to deal with scalability issues and problems associated with these large

The train of thought is similar to how we did just a straight Q-in-Q tunnel, but now, with EtherChannel, we need
