You'll want to use babble over unicast anyway. As far as the `ifconfig wg0 link1` trick I added yesterday goes... I'm not totally convinced I'll keep that yet for the next snapshot. Does bird completely ignore interfaces without it? Is there no setting to change that? Ptp isn't quite a correct match for WireGuard, so having that flag to satisfy a misbehaving userspace seems like a bummer. Have you looked everywhere within bird first to see if there's another way?
