Good morning NDN community,
I choose miniNDN to begin my experience, but surely for my poor use of
the tool, I am obtaining unexpected results.
I launched the program already written pingAll in a my personal
topology composed by two nodes connected by a link.
It is a simple scenario, but I have the same following problem with
the default topology: all the requests are nacked. For example:
PING /ndn/edu/b
20160906T113355.728806 - nack from /ndn/edu/b: seq=7022016325669868656
time=25.3841 ms reason=NoRoute
[...]
10 packets transmitted, 0 received, 10 nacked, 0% packet loss, 100%
nacked, time 0 ms
NLSR converged successfully, and the FIB table of A and B seems ok.
However I wrote them below.
mininet> a nfd-status -b
FIB:
/ndn/NLSR/sync nexthops={faceid=257 (cost=0), faceid=260 (cost=10)}
/localhost/nfd/rib nexthops={faceid=256 (cost=0)}
/ndn/NLSR/LSA nexthops={faceid=260 (cost=10)}
/ndn/broadcast/KEYS nexthops={faceid=257 (cost=0), faceid=260 (cost=10)}
/ndn/NLSR/LSA/edu/%C1.Router/cs/a nexthops={faceid=257 (cost=0)}
/ndn/edu/%C1.Router/cs/b nexthops={faceid=260 (cost=10)}
/localhost/nfd nexthops={faceid=1 (cost=0)}
/ndn/edu/b nexthops={faceid=260 (cost=10)}
/localhost/nlsr nexthops={faceid=257 (cost=0)}
/ndn/edu/%C1.Router/cs/a nexthops={faceid=257 (cost=0)}
mininet> b nfd-status -b
FIB:
/ndn/NLSR/sync nexthops={faceid=257 (cost=0), faceid=260 (cost=10)}
/localhost/nfd/rib nexthops={faceid=256 (cost=0)}
/ndn/NLSR/LSA nexthops={faceid=260 (cost=10)}
/ndn/broadcast/KEYS nexthops={faceid=257 (cost=0), faceid=260 (cost=10)}
/ndn/edu/%C1.Router/cs/b nexthops={faceid=257 (cost=0)}
/ndn/edu/a nexthops={faceid=260 (cost=10)}
/localhost/nfd nexthops={faceid=1 (cost=0)}
/localhost/nlsr nexthops={faceid=257 (cost=0)}
/ndn/edu/%C1.Router/cs/a nexthops={faceid=260 (cost=10)}
/ndn/NLSR/LSA/edu/%C1.Router/cs/b nexthops={faceid=257 (cost=0)}
Any ideas? Thank you very much
