[Nfd-dev] NDN certificate & auto prefix propagation

Mon Jan 23 07:36:07 PST 2017

Hi Junxiao,

  Thanks. I forgot to do 'nfdc register /localhop/nfd udp4://ndnx.cs.illinois.edu'.
  Unfortunately, even with that, it is not working (cannot find the prefix in the router status page)

  Here is the ndndump result at the illinois ndn node after executing ndnpingserver.

Hi Jongdeog

You never tell the P that F is a testbed router by registering a /localhop/nfd route.
See Let the World Reach Your NFD<https://urldefense.proofpoint.com/v2/url?u=https-3A__yoursunny.com_t_2016_nfd-2Dprefix_&d=DwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=Z7ZyWHGeVXO4-LRL2FeI1ZE8d269MMOL_mjEf1LVJpE&m=0rQcv-WCZ7t0cVhSKB28pTRRgN_QS3JXIAQICEzrzfk&s=WLNjQT6w4TAlRrgSWT9vpuA_dAQYC5s2ovjwOqiK1jo&e=> “how to trigger a propagation” section.

Dear all,

  Hope all of you are doing good. I have a question for NDN certificates & auto prefix propagation issue.

  Suppose that we have three machines: producer (P), consumer (C), and forwarder (F).

  What I did are followings:

1. P: the valid certificate is installed (/ndn/edu/illinois/jlee700).
    (check here: https://ndncert.named-data.net/cert/list/html<https://urldefense.proofpoint.com/v2/url?u=https-3A__ndncert.named-2Ddata.net_cert_list_html&d=DwMFaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=Z7ZyWHGeVXO4-LRL2FeI1ZE8d269MMOL_mjEf1LVJpE&m=0rQcv-WCZ7t0cVhSKB28pTRRgN_QS3JXIAQICEzrzfk&s=-0dDA0cy_hgZTqK6RKHXGEI-tXyRSOCncqVkVj9ZfJ8&e=>)
2. P: nfdc register /ndn/edu/illinois/jlee700 tcp://forwarder's<UrlBlockedError.aspx> IP.
3. P: ndnpingserver /ndn/edu/illinois/jlee700/test
4. C: nfdc register /ndn/edu/illinois/jlee700 tcp://forwarder's<UrlBlockedError.aspx> IP.
5. C: ndnping /ndn/edu/illinois/jlee700/test  (NOT WORKING)

  The problem is /ndn/edu/illinois/jlee700 is not registered on F's fib.
  This worked before (3 months ago), but now is not working.
  Any helps would be appreciated.

Best wishes,
