[quagga-dev 16599] [OSPF] How to deny/permit routes in LS packet?

Hi all,
Please help me...

This is my routing table
===================================================
K>* 0.0.0.0/0 via 192.168.4.53, usb0
C>* 127.0.0.0/8 is directly connected, lo
C>* 192.168.1.0/24 is directly connected, br0
O   192.168.3.0/24 [110/10] is directly connected, gretunnel, 00:02:40
C>* 192.168.3.0/24 is directly connected, gretunnel
C>* 192.168.4.52/30 is directly connected, usb0
K>* 192.168.6.143/32 via 192.168.4.53, usb0
===================================================
If I don't want to send the route "192.168.4.52/30" to peer OSPF server,
how can I do?

If I receive some route information from peer OSPF server, but I don't want
them, how can I deny them?

Are there any configure setting or example files in quagga?

Thanks
