    Applications Should You Bridge or Route? When connecting two Local Area Networks together, the first question to ask is should I bridge or route? The decision to bridge or to route may be decided by how the existing networks have been already set up. Bridging should be used when the network consists of non-routable protocols or routable protocols using the same network numbers.

    LAN traffic to be re-broadcast again and again causing network congestion. P850 is pre-configured to operate as an Ethernet bridge compatible with the IEEE 802.1d Spanning Tree Protocol definitions. This means that without configuration modifications, the P850 will bridge Ethernet traffic to its partner bridges when the Wide Area Network (WAN) connection has been established.
  • Page 36 Applications The P850 router also is pre-configured as an IPX router. This means that if you wish to bridge IPX traffic instead of routing it, you must disable the IPX routing function of the P850 router. Once IPX routing has been disabled, all IPX traffic will be bridged between partner bridges on the WAN.
