As soon as an Interest with Link reaches a router within the producer region, the router should delete the Link object and forward the Interest without Link.
The end host will not see the Link object and can forward the Interest to a local producer without requiring network region table configuration.

After #3162, the PIT entry should be created for the Interest without Link object:

  • If there is another Interest for the same data and with LinkObject with another delegation that is part of NetworkRegionsTable, then it should be aggregated
  • If delegation is not in the NetworkRegionsTable, then a separate PIT entry should be created

https://gerrit.named-data.net/3649 upgrades Link object forwarding test case to use TopologyTester, since it will no longer be confined with a single function.
https://gerrit.named-data.net/3650 changes incoming Interest pipeline to strip Link object when Interest reaches producer region. Incoming Interest pipeline is the right place because Link object must be stripped before deciding which PIT entry the Interest should belong to, as indicated in note-2.
