Hi, I’m replying to list for relevant benefit/discussion.
Wow, my example config is over 5 years old now…something probably changed in
syntax requirements over the years, as this is what we currently have in place
(note that a pipe isn’t used, as we now leverage "ip rule" to separately
include the blacklist table):
table blackholes;
…
protocol kernel kblackholes {
table blackholes;
kernel table 10;
scan time 10;
learn;
import all;
export all;
}
...
filter bgp_out_upstream {
if (proto = "kblackholes" ) then
{
if net.len = 32 then {
bgp_community.add((64665,666)); # Replace 64665,666 with your
upstream's community designation…if needed, otherwise delete this line
printn “Blackhole nulling ";
print net;
accept;
}
}
if net ~ [192.168.0.0/16] then accept; …replace this with your own
netblocks, one netblock per entry
reject;
}
...
protocol bgp upstream {
...
export filter bgp_out_upstream;
...
}
