Static Route /24

[Charles van Niman]

Hey Mike,

   Not sure what platform you're running BIRD on, but in Ubuntu/Linux, I
use loopback interfaces to do this. Here is what my interfaces file / BIRD
config look like. I am using /32s, but I don't think there are any issues
with /24s going into BGP. Let me know if you have any questions or I missed
your questions in some way.


/etc/network/interfaces:
# The loopback network interface
auto lo
iface lo inet loopback

auto lo:10
iface lo:10 inet static
        address 172.22.150.126
        netmask 255.255.255.255

auto lo:11
iface lo:11 inet static
        address 172.27.255.29
        netmask 255.255.255.255

auto lo:20
iface lo:20 inet static
        address 172.22.150.119
        netmask 255.255.255.255

bird.conf:

protocol direct {
  interface "lo*";
}
