[Ndn-interest] Sending data over physical interface

[Lee, Jongdeog]

Dear Prof. Lixia Zhang and Spyros,

Thanks for the reply.
I think my example confused both of you. I need a routing protocol.

Let's have 4 nodes instead of 2. The following is the topology:

/A -- /B
 |       |
/C -- /D

When all 4 nodes run NLSR and they are physically connected as above, what extra steps should I take to send packets over the links?
Does it automatically create a face ID (without nfdc command)? Or should I create it manually?
Once the face is registered, the route is automatically added by NLSR, I guess?

Best wishes,
Jongdeog Lee (JD)

JD,

if your topology is simple as you said (2 nodes), you can directly send packets from one node to the other.

NFD should have created ethernet faces and you use the nfdc command to establish a new route through the ethernet face directly (i.e., run NDN over L2). You do not need a routing protocol for such a simple scenario.

Hope this helps,

Hi all,

  Hope all of you are doing good.
  Sorry in advance if this question is duplicate.

  I would like to send NDN interest/data packets over physical interfaces, not TCP/UDP pipes.
  Suppose that we have two directly connected nodes over the wireless medium.
  Both nodes have nfd, ndn-cxx, and nlsr (chronosync and psync accordingly) installed.

  If I run nlsr on both nodes, then do these forward NDN packets to each other without any extra configurations?
  Or should I create the face and add a route on each node using nfdc command?

Best wishes,
