Hey, I'm working on the rules and routes to implement what I've been talking about, and I've got a small question about the ip rule add. I'm trying to add a blackhole route, and ip rule add seems to insist that I provide a lookup table with the route. For instance If I execute the command: "ip rule add from 0.0.0.0/0 type blackhole." when I look at what it did with "ip rule ls" I see "from all lookup main blackhole" The only way it seems to get rid of main in the example above is to define a dummy table and re-add the route like so: "ip rule add from 0.0.0.0/0 lookup bit-bucket type blackhole." Then when I see what's done with "ip rule ls" it says: "from all lookup bit-bucket blackhole" I suppose that's OK. Just seems a bit stilted. Does it matter that the bit-bucket table might not contain any routes? In the case of a blackhole route, does the kernel even perform the table lookup? Would leaving the default main in have been OK? -Andrew
