Hi Mini-NDN teams,

May I ask a question about Mini-NDN and NDN-Traffic-Generator?

I tried a simple topology in Mini-NDN, the topology configuration file looks like this:

[nodes]
a: _ radius=0.5 angle=2.64159265359
b: _ radius=0.6 angle=3.64159265359
c: _ radius=1 angle=1.57079632679
d: _ radius=1 angle=4.71238898038
[links]
a:b delay=10ms
a:c delay=10ms
b:d delay=10ms

I tried to run the ndn-traffic-server on node a:
a ndn-traffic-server /home/demi/NDN-traffic-generator/ndn-traffic-server.conf


The result on node a is:

Environment variable NDN_TRAFFIC_LOGFOLDER not set.
Using default output for logging.
2020-Aug-12 21:05:05 - Reading traffic configuration file: /home/demi/ndn-traffic-generator/ndn-traffic-server.conf
2020-Aug-12 21:05:05 - Traffic configuration file processing completed.

Traffic Pattern Type #1
Name=/example/A, ContentType=1, ContentBytes=1000000<tel:1000000>, Content=AAAAAAAA, SigningInfo=

Traffic Pattern Type #2
Name=/example/B, ContentType=2, ContentBytes=1000000<tel:1000000>, Content=BBBBBBBB, SigningInfo=

Traffic Pattern Type #3
Name=/example/C, ContentType=3, ContentBytes=1000000<tel:1000000>, Content=CCCCCCCC, SigningInfo=

Traffic Pattern Type #4
Name=/example/D, ContentType=4, ContentBytes=1000000<tel:1000000>, Content=DDDDDDDD, SigningInfo=

Traffic Pattern Type #5
Name=/example/E, ContentType=5, ContentBytes=1000000<tel:1000000>, Content=EEEEEEEE, SigningInfo=


Then I run ndn-traffic-client on node c:
c ndn-traffic-client --count=10 /home/demi/ndn-traffic-generator/ndn-traffic-client.conf

However, the result on node c is:
2020-Aug-12 21:07:41 - Sending Interest   - PatternType=2, GlobalID=1, LocalID=1, Name=/example/B
2020-Aug-12 21:07:41 - Interest Nack'd    - PatternType=2, GlobalID=1, LocalID=1, Name=/example/B, NackReason=NoRoute
2020-Aug-12 21:07:42 - Sending Interest   - PatternType=3, GlobalID=2, LocalID=1, Name=/example/C
2020-Aug-12 21:07:42 - Interest Nack'd    - PatternType=3, GlobalID=2, LocalID=1, Name=/example/C, NackReason=NoRoute
2020-Aug-12 21:07:43 - Sending Interest   - PatternType=3, GlobalID=3, LocalID=2, Name=/example/C
2020-Aug-12 21:07:43 - Interest Nack'd    - PatternType=3, GlobalID=3, LocalID=2, Name=/example/C, NackReason=NoRoute
2020-Aug-12 21:07:44 - Sending Interest   - PatternType=1, GlobalID=4, LocalID=1, Name=/example/A
2020-Aug-12 21:07:44 - Interest Nack'd    - PatternType=1, GlobalID=4, LocalID=1, Name=/example/A, NackReason=NoRoute

I am confused that why it shows NoRoute even though node a and node c connect with each other.


Besides, I checked the FIB of node a and node c. For node a, it has:
/example/A nexthops={faceid=275 (cost=0)}
/example/B nexthops={faceid=275 (cost=0)}
/example/C nexthops={faceid=275 (cost=0)}
/example/D nexthops={faceid=275 (cost=0)}
/example/E nexthops={faceid=275 (cost=0)}

However, for node c, its FIB doesn’t include above prefixes.

Could you please help me to solve the problem? Any help will be appreciated.
Thank you very much for your time.

Best wishes,
Jiacheng
