OSPF dialup non-contiguous subnets?

This weekend went to OSPF and hopefully I can solve my own mystery of
vanishing subnets. I can do everything I want quite simply but I can't
seem to route two non-contiguous subnets down a single dialup PPP
network connection. Currently this is being done quite
reliably with static routes in each of the PM2s that the customer might
connect to and an IRX router that listens to them all. The static
network routes don't come to life until the dialup connection is made
from the distant router.

I don't see how to do this with OSPF. If I put two Framed-Route records
in, it only uses the last one, so that's out. Somehow I expect this has
to do with ranges as I don't understand them or see why they are used.
Particularly as you are limited to 8 in any one area (by trial and error
although the manual says 4).

Can anyone suggest how to do this or where I can find references that
address doing this on portmasters explicitly? Have already read the
comline manual, all the archive posts and the Cisco stuff.

Please copy email as I only get digest of group.
