Hi,


In bird i have in routing table:

10.10.96.0/22     dev vlan13 [direct1 Nov19] * (240)
10.10.96.0/19     dev vlan14 [static1 09:12] * (200)

and i try to export  prefix 10.10.96.0/19 to ospf

protocol ospf test {

         import filter ospf_test_import;
         export filter ospf_test_export;


filter ospf_test_export {
         if  net ~ 10.10.96.0/19 then { accept; }
         else reject;
}

protocol static {
         import all;
         export all;
         route 10.10.96.0/19 via "vlan304";
	#test#not#helped  route 10.10.96.0/22 reject;
}

and on others ospf routers i see only:

Extern   10.10.96.0       mask 255.255.252.0




There is some limit in bird or ospf or bird takes just more precise 
route ? I'm not sure, but for a while, when i started testing this, i 
saw /19 but it was a night and i was very tired..

thanks for help
Peter
