Hello,
i'm new to bird and try to setup an OSPF Setup with 4 instances of bird on Linux Systems. The used version is 1.3.8 installed trough the Debian Squeeze Repo provided by bird.network.cz.
At the moment i tried to establish an export filter for OSPF, and it seems, that it isn't working at all. Same filter works best as an import filter:
filter notrans { if net ~ [ 10.110.1.0/24+ ] then reject; accept; }
I want this net (and all subnets) not exported to other nodes in the OSPF Areas.
I tried to test the filter on the system where i will export some routes. ... 10.110.1.64/26 via 10.110.1.178 on eth1 [transospf 18:20] * IA (150/20) [10.110.1.118] << this should not happen i think! 172.27.128.96/27 via 10.110.1.178 on eth1 [transospf 18:20] ! IA ...
For OSPF, the export filter controls just the propagation of external routes to OSPF. If some OSPF-claimed iface uses that prefix, OSPF will propagate that regardless of filters.
