Sure! r1, r2, and r3 are FRR clients. BGP relationships are successfully formed
and BGP routes are exchanged, but no flowspec is seen on the clients. I am
currently analyzing packet captures, but still haven’t completely understood
where in the packet header the flowspec is/should be.
log syslog all;
router id 4.4.4.4;
protocol device {
scan time 10;
}
flow4 table flowtab4;
protocol static flowspec4{
flow4 {
import all;
export all;
};
route flow4 {
dst 172.16.0.1/32;
}{
bgp_ext_community.add((generic, 0x80060000, 0x0));
};
}
template bgp bgp_fs_temp {
local as 4;
ipv4 {
import all;
export all;
};
flow4 {
table flowtab4;
import none;
export all;
};
}
protocol bgp r1 from bgp_fs_temp {
neighbor 172.16.4.2 as 1;
}
protocol bgp r2 from bgp_fs_temp {
neighbor 172.16.4.6 as 2;
}
protocol bgp r3 from bgp_fs_temp {
neighbor 172.16.4.10 as 3;
Thank you!

can you share your config file to let us check?

Hello,
I am seeking to setup BIRD as a flowspec manager to send messages to FRR acting
as a flowspec client. However, upon successful configuration of BGP
relationships and advertising BGP routes, FRR is not able to see any flowspec
rules. Is there a way to check to make sure BIRD is actually sending the
flowspec rules with the BGP advertisements?
Thanks!
Noris
