+# /localhost scope scenario
+
+Topology: A-B. All are NDN nodes.
+
+## Incoming scope control
+
+1. On host B, start NFD.
+2. On host B, start ndn-traffic-server to serve `ndn:/localhost/test-in`.
+3. On host A, start [socat](http://linux.die.net/man/1/socat) to create a relay from a listening UNIX socket to TCP hostB:6363.  
+   Write the path of this UNIX socket to `$HOME/.ndn/client.conf`.
+4. On host A, invoke ndn-tlv-peek to request `ndn:/localhost/test-in/A`.  
+   Fail if Interest is answered.
+5. On host B, stop ndn-traffic-server.  
+   Fail if total served Interest does not equal 0.
+6. On host A, kill socat and restore `$HOME/.ndn/client.conf`.
+
+## Outgoing scope control
+
+1. On host A, start [netcat](http://linux.die.net/man/1/nc) to listen on TCP port 6363.  
+   Redirect netcat output into a file.
+2. On host B, invoke nfdc to create face tcp://hostA:6363.  
+   Fail if nfdc fails.
+3. On host B, invoke nfdc to add nexthop for `ndn:/` toward face created in step 8.  
+   Fail if nfdc fails.
+4. On host B, invoke nfdc to add nexthop for `ndn:/localhost/test-out` toward face created in step 8.  
+   Do not fail if nfdc fails (forwarder MAY reject prefix registration that violates scope control).
+5. On host B, invoke ndn-tlv-peek to request `ndn:/localhost/test-out/B/c39b6fed4ce4464ea136062f80002c7c`.
+6. On host B, invoke ndn-tlv-peek to request `ndn:/localhost/C/c39b6fed4ce4464ea136062f80002c7c`.
+7. On host B, invoke ndn-tlv-peek to request `ndn:/ref-out/D/3b5fe3f184ff48adb3523180dee50555`.
+8. On host A, stop netcat.  
+   Search netcat output for string "c39b6fed4ce4464ea136062f80002c7c". Fail if this string exists.  
+   Search netcat output for string "3b5fe3f184ff48adb3523180dee50555". Fail if this string does not exist.
