This is one of the reasons why I keep my configs on a server, preferably UNIX. It's a trivial matter to define Nortonvirus as a macro string when you write a config, which then runs through a macro processor before the configuration goes into the router by TFTP or Telnet. The macro processor will substitute whatever you've told it -- once -- what "Nortonvirus" maps to. In like manner, you can write your standard passwords, access lists, etc., as macros. The configurations you actually read and write (as a human) become much easier to follow.
