subdivided the LAN into 2 subnets, Subnet 1 and Subnet 2. Now divide, Subnet 2 into two variable length subnets with Subnet 2a having one half of the Subnet 2 addresses and Subnet 2b having one fourth. Write down the Subnet IDs, Host IDs, and Broadcast Addresses for these Subnets (Subnet 2a and Subnet 2b). Write “Unused addresses” for the remaining addresses.

Please solve correctly. Question: A data of the size 3660 bytes, excluding 24 bytes of header, arrives at router R1. Now R1needs to send this datagram through its link which has the MTU of 600 bytes. So therouter R1 has to fragment the datagram received.I. Calculate how many fragments will the router R1 have to create to send the datathrough the link?II. Calculate the bytes of data sent in the last packet?III. Determine the fragment offset and more fragment bit of the 3rd fragment?
