Using FreeBSD as a router

[Steffen Schumacher]

Hi!

This may b the wrong list, but you might know the right one..

I'm using the port quagge (zebra spin-off) in order to run bgp
off of two freebsd boxes, serving as routers.
They receive a default candidate from bgp: a/b.
The aim is to configure a static default with a next-hop of a/b.
This way the isp doesn't have to announce a 0/0, and I will still
have a default pointing the right way.
(I'm getting the a/b in from two separate lines for redundancy).

My problem is that I can't make the default work.
I use 'route default a/b' which actually shows up in 'netstat -rnf inet'
but it still doesn't work.
I've enclosed a lot of debug output.

Can anyone point me in the right direction?

Debug output:
g3# route add default 195.249.0.0
add net default: gateway 195.249.0.0
g3# netstat -rnf inet
