That sounds like this:

"    When started (or when a network interface is later turned on),  
routed
      uses an AF_ROUTE address family facility to find those directly  
connected
      interfaces configured into the system and marked "up".  It adds  
necessary
      routes for the interfaces to the kernel routing table.  Soon  
after being
      first started, and provided there is at least one interface on  
which RIP
      has not been disabled, routed deletes all pre-existing non- 
static routes
      in kernel table.  Static routes in the kernel table are  
preserved and
      included in RIP responses if they have a valid RIP metric (see  
route(8))."

Do you have a need to perform dynamic routing?  Most people don't...a  
static route to a default gateway works fine.
