Distance vector routing is used for the six nodes given below, connected as shown in the figure. The following vectors have just come into router C from B: (5, 0, 7, 11, 10, 7); from D: (15, 11, 4, 0, 10, 11); and from E: (5, 10, 6, 10, 0, 3). Each vector contains the distances from a certain node to the other nodes, in the order of (A, B, C, D, E, F). The distances from C to B, D, and E, are 7, 4, and 6, respectively. What is the new vector for C: Use a list of outgoing lines to use and the expected distances from C to the other nodes, one entry per line for this would be clear enough and there is no need to draw a figure.

1.0. Suppose the network is as follows, where distance-vector
routing update is used. Each link has cost 1, and each router has
entries in its forwarding table only for its immediate neighbors
(so A’s table contains 〈B,B,1〉, 〈D,D,1〉 and B’s table contains
〈A,A,1〉, 〈C,C,1〉).
(a). Suppose each node creates a report from its initial
configuration and sends that to each of its neighbors. What will
each node’s forwarding table be after this set of exchanges? The
exchanges, in other words,...
