If you are trying to shape 10G links with an Debian box, apart from routing 
... you will have to do lot tunning on the system.

Look for 'High performance Linux routing' on google, you will find lot of
articles explain the caveats you will face.

When going over 1G links ... it's better to use dedicated hardware for rouiting
and shaping, IMHO.
