MANAGED, HIGH-SPEED NETWORK MODEM USER GUIDE

The network design and table entries should be planned prior to fill- ing out the static routing tables on the Modem Configuration screen. Routing table entries are also required for the gateway router and for the other routers reachable through the XL-12000S.

1. Basic Bridging

In the bridge mode, the XL-12000S modem functions as a bridge connecting two parts of the same network. This selection allows the modem to pass both IP and non-IP packets. Examples of non-IP include Novell’s IPXTM and Apple’s AppleTalkTM.

Bridging Example One (Basic Bridging):

This example shows how the XL-12000S connects two LANs in sep- arate buildings. Two types of data traffic will be sent between LANs:

Broadcast packets, which are packets sent to all LAN devices.

Direct packets, which are sent to one or several LAN devices. Direct packets will only cross the DSL link if the recipient is on a different LAN segment from the sender. Spanning Tree Protocol (STP) may be on or off in this example.
