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.
