$ nfd-status -br
FIB:
  /localhost/nfd nexthops={faceid=1 (cost=0)}
  /localhop/nfd/rib nexthops={faceid=263 (cost=0)}
  /a/b nexthops={faceid=339 (cost=0)}
  /a/b/c nexthops={faceid=338 (cost=0), faceid=339 (cost=0)}
  /localhost/nfd/rib nexthops={faceid=263 (cost=0)}
RIB:
  /localhost/nfd/rib route={faceid=263 (origin=0 cost=0 ChildInherit)}
  /localhop/nfd/rib route={faceid=263 (origin=0 cost=0 ChildInherit)}
  /a/b/c route={faceid=338 (origin=0 cost=0 ChildInherit)}
  /a/b route={faceid=339 (origin=0 cost=0 ChildInherit)}
$ ndn-tlv-peek -p -f -r /a/b/c; echo ""

Makes sense (I was looking at the RIB). I tried to modify this by adding Capture flags to both prefixes, then either one, but found that the FIB entry still contains both faces. Isn't there a way for the Capture flag to limit the faces in that FIB entry?

Here is my quick experiment that does not confirm the issue:

Before

[cawka@alex ndn-cxx (master)]$ nfd-status -br
FIB:
  /localhost/nfd nexthops={faceid=1 (cost=0)}
  /localhost/nfd/rib nexthops={faceid=264 (cost=0)}
RIB:
  /localhost/nfd/rib route={faceid=264 (origin=0 cost=0 ChildInherit)}

After

[cawka@alex ndn-cxx (master)]$ nfd-status -br
FIB:
  /localhost/nfd nexthops={faceid=1 (cost=0)}
  /a/b nexthops={faceid=254 (cost=0)}
  /a/b/c nexthops={faceid=255 (cost=0)}
  /localhost/nfd/rib nexthops={faceid=264 (cost=0)}
RIB:
  /localhost/nfd/rib route={faceid=264 (origin=0 cost=0 ChildInherit)}
  /a/b/c route={faceid=255 (origin=255 cost=0 ChildInherit RibCapture)}
  /a/b route={faceid=254 (origin=255 cost=0 ChildInherit RibCapture)}

Ok, I'll look into the CCL code; I am using .setCapture(true) but I'm seeing what I describe; BTW what is .setCaptureOk() for?

.setCaptureOk should refer to CCN_FORW_CAPTURE_OK, which is not supported by NFD.

Please send further questions about CCL to ndn-lib mailing list.
