Router Configuration
This section describes how to configure the IAD as a router. You may
configure the IAD as a router or a bridge, depending on your application.
configure the IAD as a router or a bridge, depending on your application.
Optionally, you may also configure some ports for routing and some ports for
bridging. For example, you might use a bridge connection for Internet traffic
and use a separate routed port for remote management. Alternatively, you can
configure the bridge port on the WAN side with IPoBridge to use the bridged
connection for remote management. Refer to Basic Bridge Setup Tasks on
page 4-28.

A router is a network layer device that uses one or more metrics to determine
the optimal path along which network traffic should be forwarded. Routers
forward packets from one network to another based on network layer
information.

A router generally improves overall efficiency for a complex network, but a
bridge provides better speed and flexibility for the overall network.

Basic Router Setup Tasks
To configure the IAD as a router, complete the following tasks:
•
Configure IP addresses on the LAN and WAN ports (page 4-16)
•
Enable RIP poisoned reverse (recommended) (page 4-20), add a static route
(page 4-18), or add a default route (page 4-19)
(page 4-18), or add a default route (page 4-19)
•
Disable bridging globally (page 4-31) or by port (page 4-31)
