Thats because gated and unix are both stupid, in that the UP flag has
nothing to do with the link state. If you drop the UP flag (as would make
sense), then gated thinks that the interface is not there and you have 
muchos problemos. So the solution is to either:

- do manual route management from within the ppp code or...
- bring the interface down long enough for gated to clear the routes, and
then restart it.......
