[Mini-NDN] NLSR has not converged - Issue while running minindn

[Rajendran Jeeva]

Hi Ashlesh,

Thanks for the response.

I tried running the command 'a nfd-status -b' for node 'a' and for other
nodes as well. It is not displaying anything .

1. NFD status:

mininet> a nfd-status -b
mininet>


NLSR status is displaying as follow

2. NLSR status:

mininet> a nlsrc status
NLSR Status
LSDB:
  OriginRouter: /ndn/edu/%C1.Router/cs/a

    Coordinate LSA:
      info=LsaInfo(OriginRouter: /ndn/edu/%C1.Router/cs/a, SequenceNumber:
90, ExpirationPeriod: 3591936 milliseconds)
      angle=0
      radius=0

    Name LSA:
      info=LsaInfo(OriginRouter: /ndn/edu/%C1.Router/cs/a, SequenceNumber:
90, ExpirationPeriod: 3591932 milliseconds)
      name=/ndn/edu/a

  OriginRouter: /ndn/edu/%C1.Router/cs/b

3. I just tried running 'nfd' command for a node and it displayed 'Failed
to read configuration file: /usr/local/etc/ndn/nfd.conf'

mininet> a nfd
1465913606.293515 FATAL: [NFD] Failed to read configuration file:
/usr/local/etc/ndn/nfd.conf [from ../core/config-file.cpp:94 in void
nfd::ConfigFile::parse(const string&, bool)]
mininet>

I ensured again that NFD is installed when mini-ndn is installed and the
configuration is run.

Not sure whether the convergence is not happening because the conf file is
missing.

Any help would be appreciated

Thanks in advance
