[ndnSIM] ndnSIM 2.O Intermediate node generates notification message to its downstream node

[Spyridon (Spyros) Mastorakis]

Hello,

possible reason for that:

Is the notification expressed as an interest packet? If so, you have to think about its name prefix. If there is a FIB entry to an upstream node for this name prefix, it is normal to be forwarded upstream. In this case, probably you need either to change name prefix and add manually a FIB entry for that name prefix, or manually install a longer prefix match FIB entry for the name prefix of your interest.
