TCL may be a great tool to use if you have a complicated lab
and you have a programing background.
Last time I thought about it, it sounded more reasonable to check if all
routers had all info they need (i.e. routes) than to ping from every
place to every place. And you can actually do that from the confort of a
single CLI session.
You make a list of all networks that make up your lab (net and mask)
and go check (using rsh) every router's RIB for them (using show ip
route <net> <mask> and parsing the output).
Then you make a list of all routers you have and do a couple of nested
for. You only print out what's missing.
There's a gotcha. It takes time to program this, some 5 - 10 minutes.
But again, if you get a difficult IGP... this and debug ip routing
(to catch any instabilities) can help you out.
