using BIRD version 1.0.12 (1.0.12-1~bpo40+1 provided by
bird.network.cz) or 10.0.11 (debian stable) i cannot use multiple kernel
protocols. However configuration works fine with other protocols. Can
you confirm this is a bug ?
# grep -v ^\# /etc/bird.conf
log syslog { info, remote, warning, error, auth, fatal, bug };
router id 14.215.237.93;
filter funkfeuer {
if net ~ 10.12.0.0/16 then accept;
else reject;
}
table fftable;
debug protocols all;
protocol direct {
interface "eth2"; # Restrict network interfaces it works with
}
protocol kernel {
persist; # Don't remove routes on bird shutdown
scan time 20; # Scan kernel routing table every 20 seconds
import all; # Default is import all
export none; # Default is export none
}
protocol kernel {
persist; # Don't remove routes on bird shutdown
scan time 20; # Scan kernel routing table every 20 seconds
import all; # Default is import all
export none; # Default is export none
kernel table 100; # Kernel table to synchronize with
(default: main)
table fftable;
}
