What is the difference between the single-arm router model running inter-vlan routing and traditional routing?

Vlan is a two-layer concept. Different VLANs are logically isolated and cannot access each other. If you want to exchange visits, you must build a bridge through three layers, and one-arm routing is this bridge. Create as many subinterfaces as VLANs, and configure gateway addresses of corresponding VLANs respectively.

Traditional routes are all directly three layers, as long as they are notified to each other through routing protocols.
