Hello, Since the documentation doesn't specify the exact output format, could anyone please explain it to me ? 0.0.0.0/0 via 192.168.57.60 on re0 [ospfv4 11:17:31] ! E2 (150/10/10000) [192.168.100.254] via 90.150.180.20 on ng0 [kernel1 11:12:08] (10) I understand most of it, but not in detail. 1) What, for example, the exclamation mark means ? Bird mimics Juniper notation, but Juniper doesn't have exclamation mark in it, only +/-/*. (Since bird mimics the Juniper notation it would be cool if it would also print the mark meanings, like JunOS or Cisco IOS does) 2) What is the triplet (150/10/10000) ? I understand these are probably metric/cost/preference, but which is what ? Juniper here uses single metric. 3) When it comes to internal OSPF area, this field output changes to double-field one: 192.168.57.0/24 dev re0 [direct1 11:12:08] * (240) dev re0 [ospfv4 11:17:31] I (150/10) [192.168.100.254] again, which field in (150/10) is what ? Thanks.

protocol preference / OSPF distance / OSPF external distance
Note though that the preference value in bird is inverted compared to Cisco which uses administrative distance. Juniper seems to use the term preference value but have the same semantics as Cisco administrative distance. Bird preference value: higher is more preferred Cisco/Juniper AD value: lower is more preferred
3) When it comes to internal OSPF area, this field output changes to double-field one:
192.168.57.0/24 dev re0 [direct1 11:12:08] * (240) dev re0 [ospfv4 11:17:31] I (150/10) [192.168.100.254]
again, which field in (150/10) is what ?
