[Nfd-dev] AutoPrefixPropagator inside mini-NDN

[Nick Gordon]

It's signed following Junxiao's instructions:

1. Generate the key, here "/ndn/endhost"
2. Export that key as a certificate
3. Import that key into the hub router (router1)
4. Restart NFD on router1

So that hub router has the key in the keychain. I'm not sure if this
circumvents the signature verification.

John,

I have lots of NFD logs, but I'm not very skilled at reading them. What
I see is that the strategy shows this:

1487713935.381784 DEBUG: [BestRouteStrategy2]

from=265 noNextHop

I see that the end there shows no nexthops. I don't fully understand
this, because isn't that what the register command, which is from
AutoPrefixPropagator, is doing? Saying that "on this Face, you can reach
this prefix"? Do I have to do some other kind of configuration on router1?
