[Ndn-interest] Error Creating routes over ethernet faces

[Ishita Dasgupta]

Hi All,
I am trying to create routes over ethernet with interfaces that previously
had IP addresses. I remove the IP addresses from these interfaces and
have tried
restarting the nfd-daemon as well as uninstalled and re-installed NFDC . In
neither case, am I able to see the "ether" type faces on the NFDC list.
*ifconfig*

Forcing to create a face with specified local dev interface and remote
Interface's MAC address also returns internal error.

> Error 500 when creating face: Face creation failed due to internal error


I have also executed the instruction as in nfd.conf and restarted the nfd
daemon
but that doesn't help either

>  sudo setcap cap_net_raw,cap_net_admin=eip /usr/bin/nfd



Any suggestion on what I might be missing would be helpful.
