Simple How-To for BIRD routing – OSPF

log syslog all;
 
router id 1.1.1.1;
 
# Define a route filter...
filter test_filter {
    if net = 0.0.0.0/0 then reject;
    if net = 1.1.1.2/32 then reject;
else accept;
}
 
# Define another routing table
#table main;
 
protocol direct {
    interface "*"; # Restrict network interfaces it works with
}
 
protocol kernel {
    import all;
    learn; # Learn all alien routes from the kernel
  # persist; # Don't remove routes on bird shutdown
    scan time 20; # Scan kernel routing table every 20 seconds
  # import none; # Default is import all
    export all; # Default is export none
  # kernel table 254; # Kernel table to synchronize with (default: ain)
}
 
protocol device {
    scan time 10; # Scan interfaces every 10 seconds
}
 
protocol static {
   # import all;
   # export all;
   # table main; # Connect to a non-default table
     route 1.1.1.1:255.255.255.255 via "eth0";
}
 
# Pipe protocol connects two routing tables... Beware of loops.
#protocol pipe {
   # peer table testable;
   # Define what routes do we export to this protocol / import from it.
   # import all; # default is all
   # export all; # default is none
   # import none; # If you wish to disable imports
   # import filter test_filter; # Use named filter
   # import where source = RTS_DEVICE; # Use explicit filter
#}

   # tick 2;
