If node 2 were connected to two IEEE 802-type networks, QNX network bridging would automatically bridge the two networks through node 2. Compare this to the following setup, where nodes 1 and 3 are connected to separate networks, and node 2 is common to both networks. Nodes 1 and 3 aren't directly connected to each other, but they can both access node 2. In this fault-tolerant configuration, each of the four nodes can communicate directly with any other node through...
