Subject: How redistribute routes from kernel table to OSPF protocol?
1. Routes into kernel routing table
proxmox-host1:/# ip ro list
10.18.1.25 dev venet0 scope link
10.18.1.26 dev venet0 scope link
10.16.1.0/24 dev vmbr0 proto kernel scope link src 10.16.1.27
10.17.1.0/24 dev eth1 proto kernel scope link src 10.17.1.27
default via 10.16.1.1 dev vmbr0
proxmox-host1:/#
2. Bird Config file
filter export_OSPF {
# redistribute connected
if ( source = RTS_DEVICE ) then {
print net accepted:, net;
ospf_metric2 = 20;
accept;
}
# redistribute static
if ( source = RTS_STATIC_DEVICE ) then {
print net accepted:, net;
ospf_metric2 = 20;
accept;
}
if ( source = RTS_STATIC ) then {
print net accepted:, net;
ospf_metric2 = 20;
accept;
}
reject;
}
filter import_OSPF {
if ( source = RTS_OSPF_EXT2 net != 0.0.0.0/0 ) then {
print net accepted:, net;
accept;
}
reject;
}
protocol direct {
interface eth1;
interface venet0;
}
protocol kernel {
# table main;
learn; # Learn all alien routes from the kernel
device routes;
# persist off;# Don't remove routes on bird shutdown
# scan time 20; # Scan kernel routing table every 20 seconds
scan time 2;# Scan kernel routing table every 60 seconds
import all; # Default is import all
export all; # Default is export none
# kernel table 5; # Kernel table to synchronize with (default:
main)
}
protocol ospf myospf {
router id 10.17.1.27;
debug all;
export filter export_OSPF;
import filter import_OSPF;
area 0.0.0.0 {
interface eth1 {
hello 10;
retransmit 5;
cost 10;
transmit delay 1;
dead count 4;
wait 40;
type broadcast;
priority 0;
authentication cryptographic;
password ХХ;
};
};
}
3. Output bird console
bird show route all
0.0.0.0/0 via 10.16.1.1 on vmbr0 [kernel1 2012-02-22 12:47:54] *

10.17.1.0/24 dev eth1 [direct1 2012-02-22 12:47:54] * (240)
Type: device unicast univ
bird
But I don't see these routes in a bird
10.18.1.25 dev venet0 scope link
10.18.1.26 dev venet0 scope link
(Only default route present from kernel.)
It is necessary to declare these routes to OSPF neighbors.
