Hmm, I thought I checked that before dropping setting the broadcast address (too many recent IP changes). I added it back in, but I'm surprised that the default isn't the last address in the net (CIDR-wise).

I don't know what ifconfig does use as a default, but if you use the `ip' command to set up the interfaces, default broadcast address is `none' and BIRD correctly defaults that to the last address in the net. ifconfig sets the last address in the Class C, not the net. I've added a check for broadcast address sanity to BIRD (see the patch below), so that it now complains loudly if it gets an invalid one. Added, and that may stop some problems.
