Hi,
Bird from master branch ignores the default preference set in channel
for a kernel protocol, like that:
protocol kernel {
learn yes;
ipv4 {
preference 200;
import all;
export none;
};
}
Version 2.0.10 seems ok. I suppose
I made a trivial patch for the case.

Hi,
In documentation part it is written that the default for the option is
"disabled". But in the code I see it chooses the value based on

Hi,
In the meanwhile you can "catch" route changes by exporting them to some
kernel table and monitoring netlink. Or exporting them via BGP to some
software that will perform custom action on changes. There are BGP
implementations in Python and Go to my knowledge.
But I'm not sure if that is enoug

Hi,
I did some more experimenting with making aliases from cli. As I

symbols are allocated. So I need to copy it to the current config, but I
did not find suitable functions for doing that. And I make a copy for

Hi,
If I do not mistake, cf_new_symbol() has incorrect check of symbol length.
In other places where SYM_MAX_LEN is used, it is expected that leading zero
is counted in it. But the check in cf_new_symbol() allows symbol length
equal to SYM_MAX_LEN. This does not cause a problem (as I unederstand),

Some additional ideas for decorating binary strings so that they do
not resemble other statements:
@hex(...)
bin:hex(...)
BTW, if we put a string literal inside the brackets, we can mimic a
function call without dirty lexer/parser hacks:
hex("...")
Or maybe you have already agreed on something?

I allowed mixed colons with no-divider there, so hex:12:345678:90 is

Hi,
Not sure, but I would guess it can be related to the local address. It
might try to pick the first interface with such network. Could you try
your setup with some route that has the nexthop from a unique subnet
configured on the interface? At least to check if it will become
reachable or not.
Also try to enable debugging. It might log something about why it
cannot resolve the recursive route.

You can try to still have separate IPv4/IPv6 daemons and that may help

Hi,
There were reports here in the list that some BFD peers do not allow
connections from non-standard ports and bird do not choose source port
specifically. So you might need to tune your sysctl like that:
net.ipv4.ip_local_port_range = 49152 65535
Not sure if this is the case, but I would try
Hi Lukas,
Actually I saw support for TTL security in BFD code:
https://gitlab.nic.cz/labs/bird/-/blob/master/proto/bfd/packets.c#L496
And I see in your config example that you use multihop BFD, but RFC
you refer is talking about single-hop BFD usage. So it does not seem
like a bug here. Maybe the
Hi,
I want to also show some example of configuration generation:

But I think the problem with no filters is bigger when the RTR server is
out. It is not just the short period of time when the peer can announce
anything. If rpki autoreload is on it will cause all bad announces that was
rejected before to pass the filter now. And if we turn rpki autoreload off,

Hi Mark,
Actually the best route selection algorithm can be found here:
https://bird.network.cz/?get_doc&v=20&f=bird-2.html#ss2.1
And the preference is clearly noticed there. Have you looked for it in
some other place? If you describe how did you try to find it, I
believe it might help the develo
Hi Marek,
Yes, there is a change of syntax in 2.14. The notifications show you
that the return type of the function was automatically inferred.

Maybe not random, but some sorta hash will be useful here? And it
should not break the invariant mentioned by Maria. But for the hash we
still need some means to convert IP addresses to integer numbers,
because including IP into the hash seems to be reasonable.

Hi,
For example if you want to establish several sessions over different
pathes. Also my use-case is to export routes to a BGP monitoring
system, that have fixed remote IP, but I want to send "views" from my
several upstreams, each over a separate session.

Hi,
Just to be sure. 1.1.1.1 and 1.1.1.2 are not in the single /31.
Please also provide more details. What protocol output do you show? What
route do you want from R2 to R1. Please look at things like these:
show route all
show route all export
show route all protocol

Hi,
The information you provide is a bit cryptic. For example you showed
logs from r1 and r2, but the protocol names mentioned there do not
correspond to the provided configs.
As I understand, you want to export full view from R2 to R1, it is
supposedly via protocol bgp ccre1_ipv4_1, which has exp
Hi,
This statement is wrong:
peeras = ([(65535, 1000, *)].data2);
You try to pick "data2" from the communty set (= comunity filter). Filter
itself does not contain values. You need to apply it to some community list
first. Still you'll get a community list as a result. But you can pick
"data2" o
Hi all,
Maybe it can be solved by having those kernel routes in the bird
itself? So that it knows about them and choose them as the "best". In
that case it will not reexport them back to the kernel. Recent
addition of "learn all" option to kernel protocol should be helpful
here. Haven't tried such
Hi Robert,
You can import route from the kernel table and apply blackhole policy
based on its parameters like krt_metric or something else. You can
also import such routes from non-default kernel table and add it there
temporarily.

Hi all,
I noticed in the new version 'show bfd sessions' was extended with
'all' option. But I also noticed that in case of 'show protocols',
'show ospf state|topology' this option comes before [name], but for
'show bfd sessions' it is the other way. I think it would be better to
be consistent her
Hi,
Maybe Darwin would be enough for testing this? It seems to me, that is
should contain all the necessary staff used by bird. Although, I do
not have experience with Darwin.

Hi,
I think you need to start with explaining why do you want to keep
customer and upstream routes in separate tables.

Hello,
It would be helpful if you showed "ip route show" instead of "ip route
get" for your routes, so that one could see actual routes you have in
the routing table. Please also show you bird configuration.

Hi,
You do not need to define neighbors for BGP sessions explicitly in
your BFD config. They are created automatically for BGP sessions with
BFD enabled. In that case, I suppose, you won't get errors for the
missing neighbors.

Just curious. You've done "reload out" to your session after changing
the filter, right?

OK, I see that routes you showed have best from protocol ibgp. So I suppose
they received from ibgp peer, and your are sending them to ibgp peer too.
That is not allowed by default.
