Hi guys, New BIRD user here, I'm trying to use bird to build a looking glass / route collector. All my core routers (I don't have a backbone network, so they run separately) are forwarding the full table by treating the bird system as a rr client. So far, this part of it works fine. The sessions are IBGP (and multihop by nature). My problem is the fact that bird classifies the routes as unreachable (as they indeed are, but I don't intend to use them to forward) and mentions this in the birdc lookups. A sample is given at the bottom, as well as the very simple config that I'm using right now (No tables, but I intend to set up tables per peer ('location') later) My question is how should I deal with this issue? bird> show route 8.8.8.0/24 all 8.8.8.0/24 unreachable [dfw_cr_0 07:39:20 from 10.1.13.1] * (100/-) [AS15169i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 3491 15169 BGP.next_hop: 63.218.23.65 BGP.local_pref: 400 BGP.community: (3491,2000) (3491,2001) (3491,15169) unreachable [syd_ocr_0 07:40:16 from 10.2.1.217] (100/-) [AS15169i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 15169 BGP.next_hop: 103.26.68.56 BGP.med: 0 BGP.local_pref: 106 BGP.community: (58941,0) unreachable [lax_ocr_0 07:39:26 from 10.3.14.1] (100/-) [AS15169i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 15169 BGP.next_hop: 206.72.210.41 BGP.med: 0 BGP.local_pref: 108 BGP.community: (19996,19996) unreachable [jfk_ocr_0 07:39:21 from 10.4.15.1] (100/-) [AS15169i] Type: BGP unicast univ BGP.origin: IGP BGP.as_path: 174 15169 BGP.next_hop: 38.104.75.221 BGP.med: 10040 BGP.local_pref: 100 BGP.community: (174,21000) (174,22013) Current config, the macros have been removed for obvious reasons.
