Hi Sangita and Karan. Thank you for your help.

@sangita...... <sangita.engg at gmail.com> I tried to add the line in the file
you mentioned, but it returns the following error:

@Karan, I tried your script but it only returns the name of the l3trace
file.
I have already tried to use the l3trace as a first attempt, but it doesn't
contain the names of the Interest packets (Interest1 and Interest2 in my
case).

My best regards,
Zakatria
