Try using this as a template:
tclsh
!
foreach address {
x.x.x.x
x.x.x.x
x.x.x.x

Hi there,
Have you try to use the TCL script on testing the subnet 147.16.x.0?
It's
kinda strange cause the router accepted your script but didn't even
popped
out any result (even no ping unreachable). Try to post your question in
the
mailing list and see any shed some light as well, remember post your IOS
version and router model.

Hi there,
Have you test the script in your home lab or just use 2-3 routers to
test?
Actually there is no rocket-science inside, just create the script in
notepad, paste it in the each router, hit enter, then a bunch of ping
result
pop-up.
You don't need to type any additional command. The script has the
command
inside.
Try it first in a multiple routers environment then you will know.

Hi there,
In the lab, there are 6 routers and polly each router has more than 3
interfaces with ip address. So with this script, you can ping from 1
router
to all the interfaces in all routers without typing the "ping x.x.x.x"
command like 100 times. Consider the full reachability means, that mean
you
have to do the ping check from each router point of view.
You save alot of time by doing this. Consider you need to do the check
at
least twice (after finish IGP and after reboot, at min. level)

Thanks....that works...I am able to apply the script but now I need to

how to use it for testing. I mean what commands can I use for testing
full
reachability. If its just a simple ping then why not use it from exec
mode.

Hi there,
Try this,
foreach addr {
5.5.5.5 <http://5.5.5.5>
4.4.4.4 <http://4.4.4.4>
} { ping $addr }
Make sure you paste the whole script before you hit enter.

Hi there,
Yes, from my lab experience, all routers (2600&3600) (except 3550) can
run
the tcl script,
Sample that I used in the lab,
tclsh
foreach addr {
1.1.1.1 <http://1.1.1.1>
2.2.2.2 <http://2.2.2.2>
x.x.x.x
} {ping $addr}
write this script on notepad, then paste it on each router for ping
check
then input "tclq" to make sure you return to normal command mode.
Find a router and try it once or twice, you will know. It's actually
pretty
easy to get used to it.
Cheers~
