Subnetting a subnet or using variable-length subnet mask (VLSM) was designed to maximize addressing efficiency. You are required to subnet, based on the number of hosts, including router interface and WAN interface and WAN connections for the following scenario: •Toronto: 60 host addresses •Montreal: 28 host addresses •Ottawa: 12 host addresses •Vancouver: 12 host addresses •WAN1: 2 host addresses •WAN2: 2 host addresses •WAN3: 2 host addresses Using the given address block of 192.168.15.0/24, you can design an address scheme for the network to meet its requirements and save potential addresses. The data for Toronto is given to help you to fill the remaining all other columns.

- R6Fragmentation of an IP datagram takes place if its size is larger than the MTU of the subnet over which the datagram will be routed. Most IP datagram reassembly algorithms have a timer to avoid having a lost fragment tie up reassembly buffers forever. Suppose a datagram is fragmented into four fragments. The first three fragments arrive, but the last one is delayed. Eventually the timer goes off and the three fragments in the receiver's memory are discarded. A little later, the last fragment stumbles in. What should be done with it?Block Address: 192.168.16.0/24 Port to Point Link WANI Usable Hof Hosts: 2 Users LAN: Usable #of Hosts: 25 Network Address: LANI Usable #of Hosts: 100 Users Network Address: 7 Point to Point Link WAN2 Usable 4of Hosts: 2 Users LAN2: Usable #of Hosts: 50 Network Address: The network given in the above figure consists of three local area networks and two wide area networks are connected with two serial links. With an ID range 192.168.15.0/24, design an IP plan for this network. Find the network address and broadcast address, and subnet mask for each network.Keep in mind that packet reordering and reassembly occur throughout the transport phase of the TCP/IP protocol suite's operation. It is possible for a firewall to operate at a lower abstraction level, such as the Internet or data layer. Any information about a traffic stream that is out of order or has been deleted will be lost by a stateful inspection firewall that is using stateful inspection.
