Introduction
This document addresses some of the most frequently asked questions about Bridging protocols.

Q. What is the difference between Spanning Tree and Simple Learning bridging?
A. If Simple Learning is selected, the router (bridge) learns all the hardware addresses of nodes on both ports by listening to all traffic. Based on the table, it knows whether to forward from one side to the other.
The default, Spanning Tree, works in a similar way, except that it can work on networks where there are loops and multiple connections to the same network.
Q. If the four main protocols (AppleTalk, TCP/IP, IPX and DECnet) were set as "Bridging", what happens to other protocols when they arrive at the router?
A. If you turn Global Bridging on by selecting Global/Bridging of CompatiView, then turn bridging on for a port by selecting the interface/Bridging from the Device View Window of CompatiView, the router bridges LAT, NETBUI and others.
In order to specifically bridge the four main protocols, you have to turn Global Bridging on, turn bridging on for a port AND configure each protocol for bridging in the protocol port configuration.
For more detailed configuration information, consult the sections on Bridging in the CompatiView Management Software Reference Guide.
