Thanks Lixia! I will try setting  up a second consumer to request the same
data.
But, in our experiment, we need to see what happens when the same consumer
requests the same interest multiple times. I tried writing my own
implementation of a consumer, but still only the first interest is working
well and rest all interest are *not even* forwarding from the
consumer(same) itself.

Following is a log of its operation ( with my own implemention of one
consumer sending three same interest):

1: 1s 0 CustomApp:SendInterest(): [DEBUG] Sending Interest packet for
/root/%FE%00?ndn.InterestLifetime=1000&ndn.Nonce=4231791817
2: 1s 0 CustomApp:SendInterest(): [DEBUG] Sending Interest packet for
/root/%FE%00?ndn.InterestLifetime=1000&ndn.Nonce=2837832477
3: 1s 0 CustomApp:SendInterest(): [DEBUG] Sending Interest packet for
/root/%FE%00?ndn.InterestLifetime=1000&ndn.Nonce=2794407255
4: 1.01002s 1 ndn.cs.Lru:Lookup(0x1493c10, /root/%FE%00)
5: 1.02004s 2 ndn.Producer:OnInterest(0x14fce90, 0x1528ae8)
6: 1.02004s 2 ndn.Producer:OnInterest(): [INFO ] node(2) responding with
Data: /root/%FE%00
7: 1.03089s 1 ndn.cs.Lru:Add(0x1493c10, /root/%FE%00)
8: 1.04174s 0 CustomApp:OnData(): [DEBUG] Receiving Data packet for
/root/%FE%00

As, you can see from the log, only first interest is working file and rest
2 interest are *not even* forwarding from the consumer itself.

Please suggest!

Regards,
Ravi
