Consider a network with five nodes, $N1$ to $N5$, as shown as below. The network uses a Distance Vector Routing protocol. Once the routes have been stabilized, the distance vectors at different nodes are as follows. N1: $(0, 1, 7, 8, 4)$ N2: $(1, 0, 6, 7, 3)$ N3: $(7, 6, 0, 2, 6)$ ... $N3$? $(3, 2, 0, 2, 5)$ $(3, 2, 0, 2, 6)$ $(7, 2, 0, 2, 5)$ $(7, 2, 0, 2, 6)$
