[c-nsp] ATM soft-vc path selection

[Michel Renfer]

Did you try to optimize the soft-vc routing with the following 
commands?

switch(config)#atm route-optimization ?
  percentage-threshold  configure route optimization percentage
threshold

Or manually:

switch#atm route-optimization soft-connection interface atm x/x/x

cheers,
michel
