Hi Alexander,


I can confirm that bird will install the OSPF learned routes into the
routing table after applying the patch in your email:

Okay. So your configuration works as expected now?

I'll add (modified version of) this fix to FreeBSD port at the end ofthe week.

It seems that previous patch is actually not enough.
Can you try re-building port with the following patch?


2 Ondrej:
Hi, i'm a bit stuck:

For p2p interfaces, like gifX the following happens:

ifconfig gif0 inet 10.10.0.1/30 10.10.0.2

bird: (FIN) IF gre0 flags: 60000188 ip: 10.10.0.1 opposite:
10.10.0.2 brd: 10.10.0.2
^^^^^
Kernel sets broadcast address to the peer address for given p2p
interface even with non/32 masks.
This seems "reasonable".

if_connected() uses the following logic:
is peer? (IA_PEER) -> opposite ? OK!
not peer? -> not network addr ? not broadcast ? then OK!

Currently such interfaces are treated by nest as non-multiaccess,
but IA_PEER is not set.

As a result, peer address is not treated as directly connected, so
neigh_find2() returns NULL, so all LSA behind given router has their
gw zeroed, so..

What is better: ignore kernel-supplied broadcast address or set
IA_PEER for non-/32 masks and non-multiaccess media?

Hi All,

Hello!

Recently I've migrated one of my Debian Squeeze / bird 1.3.8 route
reflectors to FreeBSD 10-BETA1 / bird 1.3.11. This reflector has
multiple gre-based links, over which I advertise loopback addresses
using OSPF, which are in turn used to establish iBGP sessions. The
problem is that it seems that Bird is not installing OSPF learned routes
into the routing table, and I'm not quite sure how to proceed with this.
Please see the output below:

I've got two OSPF neighbors, which successfully initialize:

Can you show 'show interfaces' output (and compare it with real
addresses on interface?

If addresses are different, you're probably hitting the following:
https://gitlab.labs.nic.cz/labs/bird/commit/f515e22924591542a909db0deb8545386aaa576e

This fix is already merged to net/bird port (1.3.11_2) so you try to
upgrade and see if this resolves your issue.

I was already using version 1.3.11_2 from ports :) Plus, I dont think
this is the issue:
