[Nfd-dev] AutoPrefixPropagator inside mini-NDN

I can in fact confirm that the FIB on that router has no /localhop/nfd
entry:

mininet> router1 nfdc fib list
                          │
FIB:
                          │
  /localhost/nfd/rib nexthops={faceid=260 (cost=0)}
                          │
  /ndn/router1-site/%C1.Router/cs/router1 nexthops={faceid=262 (cost=0)}
                          │
  /ndn/router2-site/router2 nexthops={faceid=261 (cost=10)}
                          │
  /ndn/broadcast/KEYS nexthops={faceid=262 (cost=0), faceid=261
(cost=10)}                         │
  /localhop/ndn/NLSR/LSA nexthops={faceid=261 (cost=10)}
                          │
  /localhop/ndn/NLSR/LSA/router1-site/%C1.Router/cs/router1
nexthops={faceid=262 (cost=0)}         │
  /localhost/nfd nexthops={faceid=1 (cost=0)}
                          │
  /localhop/NLSR/sync nexthops={faceid=262 (cost=0), faceid=261
(cost=10)}                         │
  /ndn/router2-site/%C1.Router/cs/router2 nexthops={faceid=261
(cost=10)}                          │
  /localhost/nlsr nexthops={faceid=262 (cost=0)}

I don't know if that's a problem, because I see /localhost/nfd. However,
since the strategy is looking for localhop specifically, I'm unsure.

After re-running this experiment specifically to look for this message,
I can confirm several entries like this:
