Hi Just,
I've briefly looked into the configuration code and it indeed seems like
current implementation demands thread group for BFD to be named 'express'...
This is definitely an oversight and we will fix that once we have more
time on our hands.
In the meantime having the warning is probably your best option)
Thanks for spotting this and happy routing!

Hi,
I've been testing migrating to bird3. I preferred to redefine the
default threading configs so that everything is explicit, rather than
implicit. But, when I defined the ¬eress" group, I got the following
warning logged:
<WARN> Symbol 'express' overrides existing keyword
Rather than create create needless log lines, I though I would fix
that by creating my own custom thread group instead, and use that for BFD.
I created:
thread group responsive {
threads 1;
max latency 10 ms;
min time 1 ms;
max time 10 ms;
wakeup time 60 s;
}
protocol bfd {
thread group responsive;
interface "net0" {
interval 1000 ms;
multiplier 4;
};
interface "net1" {
interval 1000 ms;
multiplier 4;
};
}
However, the config validation then throws the following error:
<FATAL> Express thread group not configured and "express" not found
Is this a bug, or something I'm doing wrong ?
Thanks!
Cheers,
Just
