Hi,
In an attempt to limit it to only two interfaces, I added this:
protocol device {
interface "eth2r", "ppp0";
}
Nevertheless, "birdc show interface" displays _all_ interfaces.
But it still says Network not found. So I also added a kernel stanza:
protocol kernel {
learn;
persist;
ipv6 {export all;};
}
Now it shows routes! I have:
588-north:bird# birdc show route
BIRD 2.0.7 ready.
Table master6:
::/0 unicast [kernel1 12:10:08.587] (10)
dev ppp0
2a02:29e1:300:e922::/64 unicast [kernel1 12:10:08.587] (10)
dev eth2r
Thank you!
However, I thought that with static having
route 2a02:29e1:300:e900::/56 unreachable;
After learning the local interface addresses, bird would gather that (only) the
addresses not configured are unreachable. It says:
589-north:bird# birdc show route for 2a02:29e1:300:e918::5
BIRD 2.0.7 ready.
Table master6:
::/0 unicast [kernel1 12:10:08.587] (10)
dev ppp0
That IP should be unreachable. How do I tell it that?
Best
Ale

Hello!
It looks like you are missing "protocol device {}" which you need for BIRD to
actually know about the interfaces and assigned addresses.

Hi all,
I installed bird2 (Debian stock) and configured radv, following the documented
example.
When bird it started, it said:
Apr 24 12:36:55 31 north bird: static1: Channel ipv6 connected to table
radv_routes
Apr 24 12:36:55 31 north bird: static1: Initializing
Apr 24 12:36:55 31 north bird: radv1: Channel ipv6 connected to table
radv_routes
Apr 24 12:36:55 31 north bird: radv1: Initializing
Apr 24 12:36:55 31 north bird: static1: Starting
Apr 24 12:36:55 31 north bird: static1: State changed to up
Apr 24 12:36:55 31 north bird: radv1: Starting
Apr 24 12:36:55 31 north bird: radv1: State changed to up
Apr 24 12:36:55 30 north bird: Started
Apr 24 12:36:55 31 north bird: radv1 < interface eth2r created
Apr 24 12:36:55 31 north bird: radv1 < interface ppp0 created
No more logging. After some hours I get this:
541-north:bird# birdc show route for 2a02:29e1:300:e922::2
BIRD 2.0.7 ready.
Network not found
What does it mean? I configured static routes in the kernel. Perhaps I should
only configure them in bird.
542-north:bird# ip route get 2a02:29e1:300:e922::2
2a02:29e1:300:e922::2 from :: dev eth2r proto kernel src 2a02:29e1:300:e922::1
metric 256 pref medium
My ISP assigned to me 2a02:29e1:300:e900/56. I have a few addresses assigned
locally, and 2a02:29e1:300:e922::1 to the lan interface (eth2r), reserving that
/64 for lan hosts. A neighboring PC has 2a02:29e1:300:e922::2/64.
External routing doesn't work, but this is another question (also asked on
stackexchange: https://unix.stackexchange.com/questions/742826/ipv6-over-pppoe)
There must be something wrong in the config, which I don't know how to fix. I
paste it below. What did I get wrong?
TIA
