5.04-1. Bellman Ford Algorithm (1, part 1). Consider the scenario shown below, where at t=1, node e receives distance vectors from neighboring nodes d, b, h and f. The (old) distance vector at e (the node at the center of the network) is also shown, before receiving the new distance vector from its neighbors. Indicate which of the components of new distance vector at e below have a value of 1 after e has received the distance vectors from its neighbors and updated its own distance vector.

5.04-1. Bellman Ford
![(b) Suppose we want to implement the following behavior, and that the default configuration is that all traffic from 22.33/16 should be allowed to be forwarded by r2 to the outside
network. However, we also want to implement a higher priority rule (which would be earlier in the table, for example) so that users within the 22.33/16 network are never allowed to
connect to an external web server on port 80. Specify the flow table row entries to implement this rule, by indicating the column entries below. The * is a wildcard match, which
matches everything - you should use * over more specific answers whenever possible.
[Note: You can find more examples of problems similar to this here.]
C. v In the "source IP" column, the flow table entry should be:
A. v In the "dest. IP" column, the flow table entry should be:
D. v In the "dest port" column, the flow table entry should be:
F. V In the "action" column, the flow table entry should be:
A. 128.119/16
B. forward(1)
C. 22.33/16
D. 80
E. UDP
