In some complex networks, there is more than one gateway and multiple routes to a single destination. Maintaining the different routes by hand is difficult and error prone.
In this case, the routed daemon is helpful. However, please be careful
with it. Most routed daemons available on the net were at some point
broken and were losing routes. I have no confirmation that a working
routed is now available. Check out gated as a replacement if you
are experiencing strange route losses with routed.
I guess this will be solved soon. If you know about this issue, please inform me!
