The Difference Between Layer 2 and Layer 3 Services – Deperimeterize

Layer 2 and Layer 3 may serve as distribution or access layer switches. It is up to businesses to determine which one to choose when they are looking to build or start networks. For making this choice, several factors need to be taken into the consideration.

If a company is looking for a solution that’s straightforward to install and does not mind slower convergence of more than a couple of seconds, the layer 2 services are sufficient for the requirements of their business. But, companies that want additional features may want layer 3 service.

Benefits of layer 3 services include equal cost, multipathing and advanced QOS. They also have faster speed of convergence than other layer 2 services. They clock within 50 milliseconds. Layer 3 networks are less controllable than layer 2. Layer 3 networks are going to require users to manually manage routing protocols, in contrast to layer 2networks that utilize a spanning tree.

Your level of technical expertise is the determining factor for the type of network you should choose for your business. If you’re proficient in technical skills and can handle some additional work, a layer 3 network is well worth the investment. Layer 2 services may be a better option to those with less expertise and are looking to accomplish more.
