Continuing the previous Bellman-Ford question… Suppose the link between node B and node C goes down. Thus, the link cost between B and C is updated to “infinity”. Continue the Bellman-Ford algorithm table from the previous problem. 1. The first row in the table for this question should be exactly the same as the last row of the previous question.  2. The second row in the table for this question should also be exactly the same as the last row of the previous question EXCEPT, increment the Iteration number and change the value of the cost from B  to C to “infinity” .  3. Now, continue the Bellman Ford algorithm using this new update from Node B.  Stop after 5 new rows have been added.  For Example: In other words, if  the last row in your previous answer was Iteration 14, then the first row in this question will be the exact same row, Iteration 14. The second row in this question will be the same as Iteration 14, EXCEPT increment the Iteration number to 15 and change the value for the cost in “(next node, cost)”  for the column B  to C to infinity.  Then, continue the iterations according to the Bellman-Ford algorithm. Stop at Iteration 19.     Answer format:Choose “Table” in the question editing menu and enter the table values accordingly. Except for the first column (Iteration), each entry should have the format  (Next node, Cost). There should not be any blank entries.

In the previous question, will it converge to a stable route a second time?(This includes the cases where 1) it did converge again in your second table, or 2) you think it will converge again at some iteration after your table. ) Give a reason for your answer. Answer Format a) Will the algorithm converge to a stable route a second time? Write YES or NO: [YesorNo] b) Repeat iteration number = [IterationNumber].       If you answered YES, enter the number of the first repeat Iteration, i.e., the first       iteration after the break between B and C, where the row values do not change       from the previous iteration. (Integer, no text)       If you answered NO, enter “it never repeats” c) Enter a reason for your answer: [Reason]  (one to two sentences of text)

Consider the figure below. Assuming the IP address of R1 is R = 165.100.0.0, and the subnet mask for the network is subnet.IP = 255.255.240.0 a) Assign (make up your own) appropriate IP addresses for router $2 subnet F, subnet G and host H5(“H”). Appropriate means the addresses should not violate the protocols we have discussed for IP addresses and subnets. Note: Each of the subnets should be able to host a maximum of 280 nodes. Answer format Decimal Integer form CIDR IP address. Example 333.333.333.333/20 Chosen address for node R2: [NodeR2Address] Chosen address for node F: [NodeFAddress] Chosen address for node G: [NodeGAddress] Chosen address for node H5: [NodeH5Address]
