If you can get ip to accept a dotted-quad netmask, let me know how :)

It all seems to be CIDR, which I don't mind, but sometimes you have
dotted quad addresses to deal with and need to convert (a bit of
bitshifting does the trick nicely enough, but shouldn't be necessary,

For your routing queries, have a read of the Linux Advanced Routing and
Traffic Control howto at lartc.org - it covers just your situation,
although it is, erm, terse...

The ip command (and quagga/zebra) and the tc command seem woefully
underdocumented, but maybe I've not been looking in the right places.
