Figure 3-5 illustrates traditional routing:
1 The packet enters the bridge or router.
2 The bridge or router determines that the packet belongs to a recognized
routing protocol, so the packet is passed to the router.
3 The router examines the destination network address and forwards the
packet to the interface (port) that is connected to the destination
subnetwork.
