Problem 2 Consider, now we replace Switch 2 with Router 1 as shown in the following figure. Assume that all the hosts and the router already know MAC addresses of each other, therefore no ARP is required. The routing table is properly configured, and forwarding tables of switches are initially empty. Suppose we have the same seven events as in Problem 1. Switch 1 Router 1 Switch 3 Hub 1 3 A B C Hub 2 Hub 3 Hub 4 006 066 060 E F G H (a) How many times have Switch 1 and Switch 3 broadcasted the received frames? (Considering all seven events.) Write your solution to Problem 2 in this box (b) List the forwarding table entries of each switch after the seven events. (Fill out the tables) Switch 1 Host Interface Switch 3 Host Interface (c) At time=10, Host A sends Broadcast IP datagram in the subnet. How many hosts will receive this broadcast IP datagram excluding the sender? Write your solution to Problem 2 in this box (d) Suppose, we have the following network IP address, 11.22.33.0/27. Assign IP addresses with IP addresses and proper subnet masks to All hosts. Do not use special IP addresses for host addresses. Write your solution to Problem 2 in this box
