- There seems to be a universal myth that routing requires significantly
- more horsepower than bridging. Actually, the real-time packet forwarding
- is about the same.

- Bridging can be done transparently to the protocol, and thus one chunk
- of code works on all protocols. Routing requires separate code for
- each protocol.
