Bug #1668

Updated by Junxiao Shi over 10 years ago

Environment: OSX 10.9 

 Steps to reproduce: 

 1. Register some prefix for udp4 multicast face: 

         [cawka@cawka-mac NFD (master)]$ nfd-status -f 
         Faces: 
           faceid=1 remote=internal:// local=internal:// counters={in={0i 29d} out={19i 0d}} 
           faceid=2 remote=udp4://224.0.23.170:56363 local=udp4://10.0.0.2:56363 counters={in={0i 0d} out={0i 0d}} 
           faceid=3 remote=udp4://224.0.23.170:56363 local=udp4://127.0.0.1:56363 counters={in={0i 0d} out={0i 0d}} 
           faceid=4 remote=ether://[01:00:5e:00:17:aa] local=dev://bridge0 counters={in={0i 0d} out={0i 0d}} 
           faceid=5 remote=ether://[01:00:5e:00:17:aa] local=dev://en0 counters={in={0i 0d} out={0i 0d}} 
           faceid=6 remote=ether://[01:00:5e:00:17:aa] local=dev://en1 counters={in={0i 0d} out={0i 0d}} 
    
         [cawka@cawka-mac NFD (master)]$ nfdc register /localhop 2 
         Successful in name registration: ControlParameters(Name: /localhop, FaceId: 2, Origin: 0, Cost: 0, Flags: 1, ExpirationPeriod: 3600000 milliseconds, ) 

 2. Try to fetch some data from the registered prefix 

         [cawka@cawka-mac NFD (master)]$ ndn-tlv-peek /localhop/test 

 Expected: no data fetched and no changes in face list   
 Actual: no data fetched, but UDP4 multicast face disappears: 

     [cawka@cawka-mac NFD (master)]$ nfd-status -f 
     Faces: 
       faceid=1 remote=internal:// local=internal:// counters={in={0i 35d} out={26i 0d}} 
       faceid=3 remote=udp4://224.0.23.170:56363 local=udp4://127.0.0.1:56363 counters={in={0i 0d} out={0i 0d}} 
       faceid=4 remote=ether://[01:00:5e:00:17:aa] local=dev://bridge0 counters={in={0i 0d} out={0i 0d}} 
       faceid=5 remote=ether://[01:00:5e:00:17:aa] local=dev://en0 counters={in={0i 0d} out={0i 0d}} 
       faceid=6 remote=ether://[01:00:5e:00:17:aa] local=dev://en1 counters={in={0i 0d} out={0i 0d}} 

 The following is in NFD's log: 

     1402873627.437623 INFO: [FaceTable] Removed face id=2 remote=udp4://224.0.23.170:56363 local=udp4://10.0.0.2:56363
