Network Dictionary – Layer 3 Routing
If you say Layer 3 Routing, you look silly. Routing refers to the forwarding of packets from one network to another. Packets are Layer 3. If you are forwarding frames then that is known as switching.
When you say Layer 3 routing, you are actually saying “packet routing packets”. And that is a tautology.
So stop it. Just say routing, or Layer 3 forwarding.
I feel better now. Rant over.

According to the Department of Redundancy Department, “Layer 3 routing” is perfectly fine.
lfmao!!! so true
Actually, there could be other types of routing, especially in telco networks. It’s therefore rather important to use this terminology sometimes…

Like what ? MPLS ? MPLS is switching not routing.
Nothing like that. I was more thinking along the lines of “call routing”, SS7, PNNI routing in ATM, SDH trail rerouting, etc.
There are important things in telco networks that are not IP. When working in an environment of mixed engineers, you need to ensure that everyone is talking the same language. I have on few occasions spent time troubleshooting “routing problems” that were not what we would call that.
