Routing algorithm

Question

Consider a router based on DV algorithm.Consider a five-node network given in figure.

Assume all nodes building distance from that node to A.After initial setup suddenly either A goes down or link between A and B is cut.What are values at router B,C,D,E which they will find to distance A from that node after 3rd transmission ??

Comments

problem is here counting infinity..as per the question ...but i think question is ambiguous !

even ans should be 5 4 3 4 if problem related to only two nodes i.e. B and C.

yes , but from where 5 is coming, via E ??

@Prabhanjan_1 ans should be 5 4 5 4

5 comes from C only..

1 2 3 4

3 2 3 4

3 4 3 4

5 4 5 4

this could be probable ans : but in  question they should specify all the marics for each node then we can decide correctly.and it aslo depends on periodic update timers of each router.
