At this point we are only interested in unicast routes. We would like to be able to dump and load the forwarding tables. We have a single 288 port switch chassis for our cluster. We would like to be able to load routes for two reasons. One is to be able to do testing with a fixed set of routes. The other is that we would like to program our own routes into the switches. > > BTW, if you call ibtraceroute thousands of times it stops working. > > Any more info on how it fails ?
