Q

What's the difference between logical segmentation and physical segmentation performed by a router?

I have yet found someone who can explain, in simple terms, the difference between logical segmentation and physical segmentation performed by a router?

Physical segmentation is dividing actually but in logical it?s done superficially. Say you have two links connecting to a remote location - either you can have those two links on a separate interface or you can create sub interfaces and ride both of them on a single link but have two different networks. This is logical separation. VLANs are another good example of logical separation.
