2. Consider the following network that consists of four access networks with hosts and one point to point link interconnected by two routers. The number of hosts for the subnets are indicated in the figure. Suppose static IP addresses will be assigned to these hosts and the router interfaces from IP address block 4.1.0.0/16. a. (10 pts) Identify the subnets in the network. b. (25 pts) Assign network addresses to the subnets found in part (a) in the form a.b.c.d/m such that each subnet has enough number of IP addresses and the largest possible value is assigned to m. Access Network 1 100 hosts Access Network 3 100 hosts R1 Access Network 2 200 hosts Point to Point Link R2 Access Network 4 150 hosts
