Of course you could just do a ping to each and every IP address in your
topology.
The easiest thing to do is just create a TCL script in Notepad and paste it
in a router. It takes only 10 minutes to make, but it's really benifitial.
Because the terminal application in the lab is SecureCRT you can select a
specific column of output. What I do when I start a lab is do a: 'sh ip int
brie | ex unas', hold down the Alt key and select the column with IP
addresses. Then you can paste it in Notepad and create your little
TCL-script around it. Just as easy as Jason said
foreach i {
10.0.0.1
10.0.0.2
} { ping $i re 2 }
I always do the re 2 behind the ping so your script runs a lot faster (only
have to do 2 pings instead of 5) especially with pings that fail.
Well you can't say that's a lot of work ;-)

sounds like doing ping is much easier :)
Do we really need to know it in the LAB ?????
