You Can't Just Send DataYou Have to Send a Frame Relay Frame

In this example, Hannah will be opening a browser to connect to the www.example.com website. After using DNS to discover that www.example.com's IP address is 150.1.3.3, Hannah sends a packet to 150.1.3.3. Because 150.1.3.3 is in a different subnet, Hannah's PC sends the packet to her default gatewaynamely, R1. When R1 receives the Ethernet frame, it checks to see if errors occurred. If no errors occurred, R1 extracts the IP packet and begins the process of making a routing decision.

Figure 15-9 picks up the routing process at this point. R1 has the packet with destination address 150.1.3.3. That destination address matches the route for subnet 150.1.3.0, which lists outgoing interface Serial0, and next-hop IP address 150.1.2.2, which is R2's IP address on its serial0 interface.
