Figure 6.2 ViPR Bridge Mode Configuration.
Router Mode: Router mode offers several advantages over Bridge mode and can be used
for simple or complex networks. In Router mode, each ViPR must be configured for a
unique IP subnet. Figure 6.3 represents a ViPR router mode configuration. Ethernet
messages will be routed to the intended recipient ViPR and will be discarded by other ViPRs
that overhear the message that was not intended for them. The user can specify the route
a multiple hop message will travel and thus can channel the traffic throughout the ViPR
network to give a more reliable connection or perhaps relieve traffic congestion on a large
network. In Router mode, the user has access to the RSSI for each ViPR that is one hop
away. In Router mode, several retry mechanisms can be enabled which often yields a more
stable and reliable link. (See section 12, Network Optimization, for more details.) Also, the
user will have access to more advanced IP configuration settings such as Network Address
Translation (NAT).
