considering that metric is delay in distance vector routing algorithm,
is it possible that delay from router A to B is different from router B to A.
if yes, under which conditions??
thanks.

The algorithm assumes the graph is bidirectional. Of course, it’s possible for the delays to be different in each direction in practice: for example, if B is transmitting heavily to A, then traffic from A to B is likely to be faster than from B to A, since traffic from B will have to get in line at the end of a queue.
