For example, you might use a bridge connection for Internet trafficand use a separate routed port for remote management. Alternatively, you canconfigure the bridge port on the WAN side with IPoBridge to use the bridgedconnection for remote management. Refer to Basic Bridge Setup Tasks onpage 4-94.A router is a network layer device that uses one or more metrics to determinethe optimal path along which network traffic should be forwarded. Routersforward packets from one network to another based on network layerinformation.A router generally improves overall efficiency for a complex network, but abridge provides better speed and flexibility for the overall network.Basic Router Setup TasksTo configure the IAD as a router, complete the following tasks:• Configure IP addresses on the LAN and WAN ports (page 4-82)• Enable RIP poisoned reverse (recommended) (page 4-86), add a static route(page 4-84), or add a default route (page 4-85)• Disable bridging globally (page 4-97) or by port (page 4-97)• Disable Spanning Tree Protocol (Spanning Tree) globally (page 4-98) or byport (page 4-99)Use the flowchart below to plan your tasks, based on your routerconfiguration requirements.
