As your network begins to grow you start to see a need to logically separate different parts of your network into different broadcast domains. But what is a broadcast domains and how is it different from a collision domains? And how do I get two different broadcast domains to talk to each other? In this video blog we review what a collision domain is and understand what is needed to get two different layer 3 network segments to communicate.
Breaking up the Party with Broadcast Domains
Its not uncommon for many larger networks and even many smaller networks to have multiple layer 3 segments. These multiple networks are used to logically breakup the network to optimize performance, divide up administrative duties, or secure the networks from each other. But once you have segmented your network into multiple broadcast domains you need a router to allow traffic to get from one segment (broadcast domain) to another.
In the following video we introduce a router and discuss what changes are needed on your network to get traffic from one network segment to another. We connect a layer 2 switch to a layer 3 router and figure out what is need to make this communication happen.
Do you still have problems routing between segments? Why not let us know but leaving a comment below
