Hi all,
It seems to me that Mikhail wants to know the protocol information, in
context of which the filter is executed. And he also wants it in the export
filter, to know protocol/peer/etc.

Hi Sander,
That is dynamic BGP. You daemon accpets connections from any allowed
adress, then it will spawn a dynamic bgp protocol. It works because
the other side knows your IP and tries to connect to it.

Hello Maria,
Regarding restarts, I think the killer feature might be some sort of
restart, when bird execs a new binary, keeping all the file descriptors
open and its state somehow. So the new instance could transparently catch
up with all the running sessions, etc. It can serialize the internal s
Hi,
While waiting for the fate of the previous patches, I was thinking
about that thing about using keywords as symbols. So here is another
longread. :)
Now it is not possible to mix a keyword and a keyword as a symbol
together. Here is what I mean. With current master bird if I use

Hi,
Please look at these patches:
bytestring-hex-prefix.patch - syntax with "hex:" prefix
I allowed mixed colons with no-divider there, so hex:12:345678:90 is
allowed. As there is a distinguishing prefix here, this should not be
a problem.
Empty bytestrings are allowed too: "hex:"
bytestring-hex

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?

Hi,
Currently one can use only a predefined set of advertised options in radv
protocol, that are supported by bird's configuration. It would be
convenient to be able to specify other possible options at least manually
as a blob so one should not wait until it is supported in the code,
released, et
I think one can now write a custom function using "for" to obtain that
functionality.

Come to CSNOG 2023. Maria should give a presentation on Bird 3 there too! :)

Hi,
If you mean you insert routes into the config file, than yes, you have to
call the configuration reload yourself. Bird doesn't reload the
configuration by itself as far as I know.

It is documented in recent versions and on the bird's site too. Pay

Hi,
As far as I remember, you can set in your income filter the interface, then
the gateway (in that order) to force the interface you want.

Hi,
I doubt that strict bind option is incompatible with multihop. Do you have
some problems with it?

Hi,
With current bird's abilities you can try something like this (with correct
IPs of course):
protocol static aggr1 {
ipv4 { table master4; }
route 103.1035.59.0/24 recursive 103.1035.59.0;
route 103.1035.59.0/24 recursive 103.1035.59.1;
...
route 103.1035.59.0/24 recursive
Further update. Do not write to the file the states of dynamic protocols as
it does not have much sence.

Updated the patch for keeping state in the file. Moved the read/write
functions to sysdep/unix/main.c and made better parsing. So it is not a
draft anymore, but something more or less "stable". I can add documentation
patch in case there is interest to include that into upstream.
