<font face="Calibri">Hi guys,<br>
<br>
New BIRD user here, I'm trying to use bird to build a looking
glass / route collector.<br>
<br>
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.<br>
<br>
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.<br>
<br>
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)<br>
<br>
My question is how should I deal with this issue? <br>
<br>
