Subject: annoucing default route via gated

I have 2 machine which I want to announce a default route into a network. One
is Linux and the other is FreeBSD. The Linux machine successfully announces a
default route onto the network, whereas the FreeBSD machine will annouce any
route, EXCEPT for the default. These are with practically identical
configuration files (interface names and metrics are different).

Here's the config file I use, with the IP's changed since this is a firewall :)

traceoptions "/var/log/gated" replace size 100k files 2 general ;

interfaces {
  interface all passive ;
} ;

rip yes {
  interface all version 2 ;
  interface 192.168.192.3 noripin ripout version 2 ;
  traceoptions detail send packets ;
} ;

static {
  default gateway 192.168.142.1 preference 1 ;
} ;

export proto rip interface 192.168.192.3 {
  proto static {
    default ;
  } ;
  proto direct {
    192.168.142.0 ;
  } ;
} ;

The 192.168.142.0 route is mainly to see if it actually sends a packet. (I've
tried both with and without it)

The end result is to have the Linux machine announce a default route with a
metric 1 and the FreeBSD machine with a metric 2. It can be reversed since they
are identical machines. I'd just like to get it to work.

Now when I look at the /var/log/gated, I see this:

Jan 30 15:13:09 RIP SENT 192.168.192.3 -> 224.0.0.9+520 vers 2, cmd Response,
length 24
             192.168.142/255.255.255     router 192.168.192.3    metric  1 tag
0000
RIP SENT end of packet

The default route is absent. I've looked all through dumps and gated does
indeed see the default route and it's in the export list, however it never adds
it to the packet it sends out.

The Linux machine with a virtually identical configuration works flawlessly.
Does anyone have any idea why won't this work under FreeBSD?
