If you are confident enough that you don't want to bother pinging every
interface on all routers and switches in your rack, then skip it.
But suppose you *do* want to ping each interface. For the sake of
argument, let's say you have an average five IP addresses configured on
each of 6 routes and 2 switches, some might have more and some less.
Eight time five is forty so that means you are going to type in "ping
x.x.x.x" 40 times on each device.
Personally, I just don't type that fast. I used the script twice: Once
after finishing IGP redistribution. I found a couple of loopbacks I had
forgotten to add to an IGP. I used the script once more at the end of my
lab time with 30 minutes to go, after I had rebooted all the equipment.
There's not much to memorize, just 2 or 3 lines of code.
Type "sh ip int brief | exclude unassigned" on each device and copy the
output into notepad. The edit out the extraneous junk, add the TCL
commands and you're done. I think it took me just over 5 minutes. I then
copy and paste the script into each router as needed.
Some people set up rcmd to run the script from a single router, but I
would rather not configure anything extra on the routers, than what is
in the lab exam booklet.
HTH,
Jonathan
