Figure 36 shows an example of a client computer using IP/PPP/PPPoE and an Internet gaming system running IP, connecting to the E-series router over the same ATM PVC. The client computer and gaming system can connect to an E-series router via an xDSL modem over a single ATM PVC, and the router can forward these two data streams independently. When the router receives the two data streams, it uses the Ethertype contained in the bridged Ethernet header to select which upper interface (IP or PPPoE) receives the frame.
In Figure 36, IP and PPPoE interfaces are configured so that the non-PPPoE IP traffic is received by the IP interface, and the IP/PPP/PPPoE traffic is received by the PPPoE interface. Since the router receives these data streams on different IP interfaces, they may be routed independently.
