If the DSL link LED does not blink, see the “Troubleshooting” section. 6. When link LEDs are solid green (after several minutes) the pair of modems are operational in bridging mode.
XL-12000S MANAGED, HIGH-SPEED NETWORK MODEM USER GUIDE The network design and table entries should be planned prior to filling 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.
XL-12000S MANAGED, HIGH-SPEED NETWORK MODEM USER GUIDE The configuration for the modems used in “Bridging Example One (Basic Bridging)”: LAN IP addresses are shown in Figure 7.2 although this option does not require you to enter new LAN IP addresses : Note: If all administration and configuration of the modems is to be done via the serial Console, as opposed to Telnet and SNMP sessions, no IP, mask, or default gateway addresses need to be assigned to the modems.
XL-12000S MANAGED, HIGH-SPEED NETWORK MODEM USER GUIDE Bridging Example Two (Advanced Bridging): This example shows how two pairs of XL-12000S units connect two LANs in separate buildings. It shows the best use of the Spanning Tree Protocol (STP) by creating redundant loops in the network. This way if one link becomes unavailable, STP uses the other path to reach the destination. This configuration is ideal when network availability is critical. Figure 7.
XL-12000S MANAGED, HIGH-SPEED NETWORK MODEM USER GUIDE The configuration for the modems used in “Bridging Example Two (Advanced Bridging)”: For Modem 1: The “LAN IP address” field in the Modem Management screen will be set to 192.168.1.8 The “Subnet Mask” field in the Modem Management screen will be set to 255.255.255.0 The “Default Gateway” field in the Modem Management screen will be set to a valid default gateway.
