[Mini-NDN] NLSR Configuration File

[Ilane Karise]

Sorry for asking so many questions, it's because I could not find the
answers for myself. But, if there is any configuration of the PIT. Is there
a default size for it? How can I know which parameters to work with to
emulate interest flooding attack? This is possible?
