Thank you for replying.<br>
<br>
However, *all* of the routes are unreachable (because this is a
IBGP multihop session and it doesn't sit on the traffic path),
none of the core routers are sitting nexthop from this vm where I
installed bird.<br>

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>
