Description
Suppose a node x sends an interest with a digest that another node y does not recognize. When node y receives this interest, it sends its full old data as a reply. When node x receives this old data, it discards it -- as it finds nothing new in the data -- and resends the interest. The problem is that the old data gets cached and it keeps satisfying the interest. The interest does not travel to another node z that has the relevant new data, causing unnecessary delays.
Therefore, sending of old data in reply to interest with unrecognized digest is a bug that needs to be fixed.
