What is the difference between routing and bridging in VPN?

Could you please elaborate on the distinction between routing and bridging in a VPN setup? I'm trying to understand the fundamental differences in terms of functionality and how they affect network traffic. I'm aware that routing involves forwarding packets based on network layer information, while bridging operates at the data link layer, but I'm interested in a deeper explanation of how these mechanisms work in a VPN context. Could you provide some insights into their respective advantages and disadvantages, as well as scenarios where one might be preferred over the other? Thank you for your assistance in clarifying this topic.
