[Nfd-dev] [Ndn-interest] Problem with retrieving packets on GENI testbed

[Mohammad Alhowaidi]

I found that its working with tcp not udp, when I use
nfdc face create tcp://10.10.7.2
nfdc route add /ndn tcp://10.10.7.2

NOT
nfdc face create udp://10.10.7.2
nfdc route add /ndn udp://10.10.7.2

Any idea why it just work with tcp not udp?

Thanks,
Mohammad
