hope it helps. iproute2 is an absolute Godsend. I use the simplest of its
configurations and get what I want easily.. If you wanted to get into some
really complicated things, iproute2 has so many additional advanced config
options it could take weeks to read up on them all but from what I can
gather, it can solve the most complicated of needs and do things that
previously would have you banging your head against the wall trying to
solve :) I now use iproute2 on everything, even on simple workstation
installations, so it is there if additional configuration is ever needed.
