This is usually drawn because the side with the rook can't really force the side with the knight backwards, mostly because then the king will be subject to an avalanche of knight checks.
There are a few situations where the side with the rook can win though:
1) when the side with the knight has its king in a corner / back row (mate threats)
2) when the side with the knight has its knight in a corner (the knight should be deprived of any escape squares, after which you can pick it up)
However, if black simply keeps his knight close to his king, these situations will never occur.
