Hi, im Brasilian.

I like the Quagga project and im using in our network (Core firewalls).
I know how to configure routing filters in Quagga, but i miss some
controls like "OSPF Inbound Filtering" (for any given route).

Something like this:
http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/routmap.html

At now, Quagga cant do this.
Look this example made in Cisco router:

         router ospf 1
         ...
         distribute-list prefix IMPORT in
         ...

         ip route 10.0.0.0 255.0.0.0 10.x.y.z

         ip prefix-list IMPORT seq 5 permit 10.1.2.0/24
         ip prefix-list IMPORT seq 10 permit 10.2.0.0/16
         ip prefix-list IMPORT seq 15 permit 10.1.4.0/24
         ip prefix-list IMPORT seq 20 permit 172.31.1.0/24
         ip prefix-list IMPORT seq 25 permit 172.20.0.0/16
         ip prefix-list IMPORT seq 30 deny 10.0.0.0/8 le 32
         ip prefix-list IMPORT seq 35 deny 172.16.0.0/12 le 32
         ip prefix-list IMPORT seq 40 deny 192.168.0.0/16 le 32
         ip prefix-list IMPORT seq 45 permit 0.0.0.0/0 le 32

This works perfect in Cisco routers.
I can do the same filter in 3Com layer3 Switchs ("filter-policy
ip-prefix IMPORT import").

The result in the Cisco or 3Com corresponds *exactly* to that defined
by the filters (no matter LSA type).
Before writing, I did this test to make sure.

I cant do this filter in Quagga routers.
