Steps:

1. Start NFD on A,B,C.
2. On host A, create UDP face to host B, and add nexthop for ndn:/test-loop toward this face.
   On host B, create UDP face to host C, and add nexthop for ndn:/test-loop toward this face.
   On host C, create UDP face to host A, and add nexthop for ndn:/test-loop toward this face.
3. On every host, set strategy of ndn:/test-loop to strategy under test.
4. On host A, execute ndn-traffic-client to send 100 Interests to ndn:/test-loop/A/<random>.
5. On every host, execute "nfdc face list" to see face counters. Fail if NInInterests or NOutInterests counter of a UDP face is greater than 200.
