Description

A----10ms----B----100ms----P

A,B = consumer
P = producer

t=10ms) App on A sends interest to B, B forwards to P
t=30ms) App on B sends the same interest [different Nonce] to A and P

A receives the interest from B and rejects the PIT as there are no other next hops and interest received is not suppressed.
Later when P answers, A drops it as unsolicited.

[Reported by Lan].

Solution seems to be to reject PIT only if Interest is new.
NoRoute NACK should probably also be sent under this case only similar to other strategies.

  • Target version set to 22.02

I'm removing "retransmitted" from the issue title as I don't think the 2nd Interest can conceptually be considered a retransmission.
