ERROR: Failed to register prefix in local hub's daemon
100%
Description
The ndn-repo generated an error while it was running on OpenWRT router.
The error messages are written as follows:

Precisely, I have cross compiled the NFD, ndn-cxx and repo-ng for the OpenWRT router. All are the latest version from github. The NFD was running properly, but error messages were generated while it was running the ndn-repo-ng.
However, the ndn-repo-ng is working properly when it runs on Linux machine.
The error messages (rearrange from previous post) are written as follows:
root@NDN11:/var/db/ndn-repo-ng# ndn-repo-ng

From what I can see, you have started just nfd process, which is not enough.
You need nfd and nrd processes to be started in order for NDN applications to work properly.

I have just checked the running process on this router. The nfd and nrd processes have already run, but I still have the same error messages after running the "ndn-repo-ng" command.
Besides, I also tested with other NDN applications (i.e. ndnping, nun-traffic-geneartor), they were running properly on this mobile router.
If you need more information such as logs or nfd' status, please suggest.
Thank you

This is probably caused by repo-ng registering four separate routes into NFD-RIB, but ndn::nfd::Controller does not have stop-and-wait (#2293), cause some commands being rejected.
Another possibility is simply insufficient computation power on OpenWRT.
I'll try to address the first cause.

I decide to make a small change to fix the excessive FIB entries problem, which has bothered me in my deployments for some months.
Eventually this needs to be switched over to the dispatcher.
