Hi,
I'm experiencing bird heavy loaded and causing some delays for forward
packets. I have 03 full route sections bgp and I am route reflector for
02 other router.
This happen when bird process kernel protocol:
protocol kernel kernel4 {
#scan time 90;
learn;
persist;
ipv4 {
export filter {
if proto = "ST_BGP4" then {
#print "Reject: kernel_export: ", bgp_path, " ", source;
reject;
} else {
#if source = RTS_BGP then reject;
accept;
}
};
};
}
protocol kernel kernel6 {
#scan time 90;
learn;
persist;
ipv6 {
export filter {
if proto = "ST_BGP6" then {
#print "Reject: kernel_export: ", bgp_path, " ", source;
reject;
} else {
accept;
}
};
};
}
and if I reject routes from BPG to kernel this problem ends
From netstat -m there is this close limit:
244194K/33475K/277669K bytes allocated to network (current/cache/total)
# cat os-release

Are there any suggestion for big route FIB processed in kernel by BIRD?
Thanks,
Paulo.
