Figure 16-8 shows hub-to-remotes configuration using routers with standard and split-path
Ethernet traffic. A Static ARP Entry is needed in the switch so that routing of the Tx side of the
modems will be on the correct port of the router. For example, the Rx side of the Ethernet
connection for ‘Traffic Modem #N’ comes in the bottom port of the Router, but the Tx Ethernet
connection must be connected through the same port as ‘Traffic Modem #1’, as shown in this
figure.
