[c-nsp] ACLS for Virus

[Annu Roopa]

Hi Folks,
   
  I am trying to find out how ACLs can be implemented on a Cisco GSR or 72xx router such that any Virus attack from the ISP side could be prevented.
   
  Has anyone done anything similiar ? I am told there are ways to do this, but dont find much on CCO or Cisco site. Anyone with pointers ?
   
  Thanks for your help.
   
  Annu
