TCL Scripts aren't that bad when used effectively.
1. show ip alias (Gives us a quick list of our IP's in use)
2. Copy to Notepad
3. Search and Replace to "Massage the Data and toss in the PING Command).
4. Wrap what's left in a TCL or Macro.
5. Copy and Paste into a Router to your heart's content.
BTW - This can be deceptive when it comes to reachability, full reachability
that is. So you may want to learn and get used to using your script to
source from the appropriate "hard to reach" places in your pod.
Love those little problems where you can ping everything "from the router"
and yet not "from the interface".
