Maximum routing table sizes for ZigBee
ZigBee does not specify any maximum size for a routing table, only the minimum
requirements. In a network where one device (a Gateway) might try and
communicate with 100's or even 1000's of devices, routing table size can become
an issue as the table is stored in limited RAM. This has been addressed by
requiring one routing table entry per Router in the network, using the known
Router parent's table entry for any communication with End Devices. Therefore if
the ratio of End Devices to Routers is 10:1, then a 1000 node network would only
require approximately 100 routing table entries.

We have the issue that end devices cannot join at certain routers in the middle of our network. The routing table could have caused the problem.

I would also like to know what happens if the network is too big for the routing table.

If the network is so large that the routing table can not have one entry for each router, what will happen? For example, the routing table can hold 40 entries, but there are 200 routers.
Will the network fail to work, or the routing table works like a cache?

I was told earlier that you can read the association and routing tables (using functions in rtg.h), but you cannot manually add entries as they will have to be generated based on the ZigBee specific algorithm AODV (the algorithm used to determine the best route to be used for routing in a ZigBee network).

I used the cc 2430db and i would like to program the routing table of this board to have a fixed raod of data in the network
<how to program this table and with which tool we can do it?
