OSPF with Quagga on Linux

I am running a Linux machine as a PPPoE access concentrator.

A----------------B C----------
PPP----| Concentrator | <--OSPF--> | Router |---> Internet
---------------- ----------

Interface "A" : No IP address, PPPoE tunnels only
Interface "B" : 192.168.1.1/24
Interface "C" : 192.168.1.2/24

Interface "A" handles incoming PPPoE tunnels with endpoint addresses in the
10.0.0.0/16 and 192.168.0.0/24 ranges. ospfd advertises routes to the
addresses of these tunnels through interface "B" when the interface comes
up.

Is there a way to prevent ospfd from advertising the 10.0.0.0/16 addresses
so that the router (with interface "C") will only hear about routes to
192.168.0.0/24 ?

Relevant configuration files appended.

Any help greatly appreciated.

Charlie
