[Mini-NDN] Multi Router NLSR config

[S Khorasani]

Dear Vince,

My concern is that I have installed the source files on a new machine, not
the one that I already installed binary versions from PPA on it. So I think
that the problem is elsewhere. Could you please let me know other probable
sources of the problem?

Regards,
skh
