NFD

Topology:

B---A---C
    |
    D

It's okay to have all hosts on same Ethernet switch and in same IP subnet, but multicast must be disabled. The tunnels will have this logical topology.
All are NDN nodes.

Script is invoked on host A. Script should control other hosts over ssh.

Steps:

1. Start NFD on A,B,C,D.
2. On host B,C, start ndn-traffic-server to serve ndn:/test-bcast.
3. On host A, invoke nfdc to set BroadcastStrategy at ndn:/test-bcast.
4. On host A, invoke nfdc to create UDP tunnel to B, and add nexthop for ndn:/test-bcast to this face with cost 10.
5. On host A, invoke nfdc to create UDP tunnel to C, and add nexthop for ndn:/test-bcast to this face with cost 20.
6. On host D, invoke nfdc to create UDP tunnel to A, and add nexthop for ndn:/test-bcast to this face.
7. On host D, execute ndn-traffic-client to send 100 Interest to ndn:/test-bcast/A/<random>.
8. On host B,C, stop ndn-traffic-server. Fail if total served Interests on either host is less than 80.
9. On host D, invoke nfd-status to observe counters on the face created in step 6. Fail if total received Interests on this face is greater than 120 (because A should not forward the second copy of Data to D after PIT entry is satisfied).

Script can assume integrated test suite is cloned to all hosts, necessary programs are installed and accessible in $PATH, and current user can ssh to other hosts and has sudo privilege.
