Tickle (Tcl) your NLRI !!! :)

You can use a simple Tcl script to test connectivity between your devices:

foreach ip {
 x.x.x.x} { ping $ip

For example, below is one tcl script that I had ready to check NLRI after performing an OSPFv3 lab.


foreach ip {

 2000:44:44:44::44} {ping $ip rep 10}


There is an obvious advantage when using these kind of scripts, that is you end up saving lot of time during practise and this is also a must use tool  during ccie lab as well; especially when you want to check your basic network reachability before you break for lunch.
