Is this a switch or a router?
A basic question any network engineer will ask and i can safely say that its hard to accept the answer you generally get, and its equally hard to answer it as well, and the funny thing is how often we get this question gets asked over a period of time and we are still perplexed at the end of it.
The general answer is if you have a device configured with IP address then its a Router as it deals with L3 else its a Switch as it deals only with L2, but whats the use of configuring just the IP address when you don’t have any routing protocol? And have we seen any device without an IPv4/IPv6 address attached to it? So in the end you get confused if you got to call it a Router or Switch, thats why i guess most of the techies just stick to the term ‘Box’ most of the time, easy you see 🙂
In reality, terminology is never perfect, and it doesn’t need to be. Avoid getting hung up on ambiguous labels and learn to classify devices by the roles they fill.
Recently came across a post on PacketLife which talks about this topic and i have to say they nailed it in terms of explanation and in future if any one asks me about this I will just point them to this article, but still its a Box… 🙂
