Hello This seems like a bug in BIRD. OSPF generated routes other than E2 (type 2 external) have attribute ospf_metric2 set to LSINFINITY, but when a route is exported to OSPF and have ospf_metric2 set (even to LSINFINITY), then it is generated as E2 with given metric. We should generate ospf_metric2 attribute only for E2 routes. There is a simple workaround: In OSPF export filter, use this command: unset(ospf_metric2); That would generate E1 routes from IA routes. Or just set ospf_metric2 to a sane value to generate E2 routes. > How route is seen: > Imported from other vm host via ospf: > bird> show route table table_ospf_0 10.20.5.135/32 all > Table table_ospf_0: > 10.20.5.135/32 unicast [ospf_vm 13:52:53.209] IA (150/20) > [10.255.10.129] > via 10.133.146.12 on ospf0-br > Type: OSPF-IA univ This seems like another bug, there should be list of OSPF attributes. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santi...@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
