A co-worker was showing me the neat way that windows XP deals with mutiple connections. Instead of bringing connections up and down as cables get plugged in/waps get too far away/etc, all interfaces are brought up whenever they can be connected. So, for example, a laptop with wireless, ethernet, and a bluetooth/gprs connection will have 3 interfaces up. The routing table is set up such that all 3 routes exist, but have different metrics. So (hyptothetically) the ethernet will have a metric of 0, the wlan 20, and the bluetooth 60. When a packet is routed, it chooses the route with the lowest metric. This means that instead of losing connection, and then having to wait for a new connection, the network connection just gets re-routed to the next lowest metric connection without a break in connectivity (or at least with a noticably shorter break).
2 questions: 1) can routes in linux be set up this way? (I've only seen metrics of 0 when i run the route command, man route says the metric is not used by recent kernels...) 2) would it make sense for NM to try to do things this way?
