6.7.2.1.1.1 Router Mode (exclusive to the full-featured HiPR900 version)
In router mode, a unit detects the presence of other units with the help of the neighbor discovery module.
When a unit has detected the presence of another unit, it updates its IP routing table. A unit can learn
about any unit that is not directly reachable from a unit that is directly reachable.
Each unit keeps at most two paths to each destination. The primary path is the one with the least num-
ber of hops. If there is more than one route with the same number of hops, the newest one discovered
will be the primary route.
Note: The primary (least number of hops) path may not be the most RF reliable. The user can
toggle between the primary and backup paths.
The route that is flagged “Active” is used when installing the internal IP routes
The list of all neighbors for any given unit is displayed and accessible through the web-browser. The
user can manually switch the path to secondary route.
6.7.2.1.1.2 Bridge Mode
In Bridge mode of operation, each Unit repeats the traffic from its LAN interface to its RF interface and
vice versa (see Figure 31).
