Homework Statement
If the network layer is sending a message from A to D via B, it can be sure that a message sent by the data link layer from A to B will always arrive at B, and from B to D will always get to D. How is it possible for the network layer not to be able to correctly deliver a message from A to D.
Assume this 4-node network:
A---B----D
|...|...|
|---C ----|
ignore the periods! Basically A is connected with B and C; B is connected with A, C and D; C is connected with A, B, D; D is connected with B and C

The Attempt at a Solution
I am not sure about this one. Could it be if the two nodes arent using the same addressing scheme? Any help would be appreciated.
