NFD

Develop a integration test for route expiration.

Topology¶

B---A---C

Edges represent logical links (UDP tunnels).

Steps¶

1. start NFD (including RIB Daemon) on A,B,C
2. add routes on A
   • ndn:/P , nexthop=hostB, expiration=10s
   • ndn:/P , nexthop=hostC, expiration=20s
   • ndn:/Q , nexthop=hostB, expiration=20s
   • ndn:/R , nexthop=hostC, expiration=10s
   • ndn:/S , nexthop=hostB, expiration=3600s
3. delay 5 seconds; run nfd-status on A to inspect RIB
   Expected:
   • ndn:/P (hostB expires in 3-8s, hostC expires in 13-18s)
   • ndn:/Q (hostB expires in 13-18s)
   • ndn:/R (hostC expires in 3-8s)
   • ndn:/S (hostB expires in >3000s)
4. delay 10 seconds; run nfd-status on A to inspect RIB
   Expected:
   • ndn:/P (hostC expires in 3-8s)
   • ndn:/Q (hostB expires in 3-8s)
   • ndn:/R : entry does not exist
   • ndn:/S (hostB expires in >3000s)
5. delay 8 seconds; run nfd-status on A to inspect RIB
   Expected:
   • ndn:/P : entry does not exist
   • ndn:/Q : entry does not exist
   • ndn:/R : entry does not exist
   • ndn:/S (hostB expires in >3000s)
